+	* src/main/java/de/intevation/flys/client/client/ui/StyleEditorWindow.java:

+
+2011-12-19	Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+
+	Minor refactoring to ease addition of new (theme-style) settings.

+	flys/issue409 (Überschwemmungsfläche: Reihenfolge in Themenliste nicht immer synchron mit Rendering)
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/FloodMap.java: Added
+	  a addLayer() method which should be used to add new layers to the map. New
+	  layers are always displayed at the bottom of the layer stack.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Use FloodMap.addLayer() to add new layers instead of adding them directly
+	  to the Map.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapThemePanel.java:
+	  Removed the re-order process of map layers. This is no longer necessary,
+	  because MapOutputTab uses FloodMap.addLayer() to add new layers instead of
+	  adding new layers on its own using Map.addLayer() directly.

+
+	* src/main/java/de/intevation/flys/client/shared/model/WMSLayer.java: Added
+	  the URL of the WMS server to the constructor parameterlist, because this
+	  information is absolutely required for a WMS layer.
+
+	* src/main/java/de/intevation/flys/client/server/GCServiceImpl.java:
+	  Modified the constructor call of WMSLayer.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:

+
+	* src/main/java/de/intevation/flys/client/client/ui/map/ExternalWMSWindow.java:
+	  Defined an internal interface LayerLoader to load selected WMSLayers of

+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Implements the ExternalWMSWindow.LayerLoader interface to add the
+	  selected WMS layers to the map. TODO: implement code to load/add layers.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/WMSLayersTree.java:
+	  Added an inner class WMSLayerNode that extends TreeNode with the
+	  addition to save a WMSLayer object. The reason here: we want to have all
+	  information of the selected WMS layers for loading mechanisms.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapToolbar.java:
+	  Modified the constructor call of ExternalWMSWindow. The MapOutputTab is

+	  Do not use 'name' attribute of datacage.
+
+	* src/main/java/de/intevation/flys/client/client/widgets/tree/AttributedTreeNode.java:
+	  Removed. Not longer needed.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DatacageWindow.java:
+	  Build the UI tree in a more smartgwt compatible style. Prevents lots
+	  of exception when using click listeners.

+	  Set window title to include UUID.
+
+2011-08-09	Felix Wolfsteller	<felix.wolfsteller@intevation.de> 
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:

+
+2011-08-09	Felix Wolfsteller	<felix.wolfsteller@intevation.de> 
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties:
+	  Adjusted German translation to use unique strings.

+
+2011-08-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de> 
+
+	* src/main/java/de/intevation/flys/client/client/widgets/tree/AttributedTreeNode.java:
+	  New. Subclassed TreeNode to carry the attribute data from
+	  the meta data service.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DatacageWindow.java:
+	  Create AttributedTreeNodes instead of TreeNodes to have the
+	  relevant information at hand if a listener wants to access
+	  the data.
+
+2011-08-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

+
+2011-07-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/DefaultCollection.java,
+	  src/main/java/de/intevation/flys/client/shared/model/Collection.java:
+	  Collections are able to store the recommendations they have already
+	  loaded. Therefore, new methods have been added to add recommendations
+	  and to determine, if a recommendation has already been loaded.
+
+	* src/main/java/de/intevation/flys/client/server/DescribeCollectionServiceImpl.java:
+	  Read the already loaded recommendations from Collection's DESCRIBE
+	  document.
+
+	* src/main/java/de/intevation/flys/client/server/CollectionHelper.java:
+	  Write the Collection's recommendations into its attribute document.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Two things:
+	   1) Do no load recommendations that have already been loaded before.
+	   2) Update UI when there are no more artifacts to load (recommendations).
+
+2011-07-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/ArtifactDescriptionFactory.java:

+2011-07-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/DefaultRecommendation.java,
+	  src/main/java/de/intevation/flys/client/shared/model/Recommendation.java:
+	  New. The interface and its default implementation that represent
+	  recommendations provided by an Artifact. A recommendation consists at
+	  least of the name of an ArtifactFactory and a list of database ids.
+
+	* src/main/java/de/intevation/flys/client/server/ArtifactDescriptionFactory.java:
+	  Read the recommendations from Artifact's DESCRIBE document (which
+	  structure has changed.)
+
+	* src/main/java/de/intevation/flys/client/shared/model/ArtifactDescription.java,
+	  src/main/java/de/intevation/flys/client/shared/model/DefaultArtifactDescription.java:
+	  Recommendation are no longer simple strings but Recommendation objects
+	  now. So, the interface to retrieve those recommendations has changed.
+
+	* src/main/java/de/intevation/flys/client/client/services/ArtifactServiceAsync.java,
+	  src/main/java/de/intevation/flys/client/client/services/ArtifactService.java,
+	  src/main/java/de/intevation/flys/client/server/ArtifactServiceImpl.java:
+	  This service takes a further string now, which represents the database
+	  ids used to create static artifacts that require data from database.
+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java,
+	  src/main/java/de/intevation/flys/client/client/ui/ParameterList.java,
+	  src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:

+
+M      src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java
+
+2011-07-20  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/FloodMap.java: The
+	  vector layer which is used to save features created by the user acts as
+	  OpenLayers base layer. I decided to do so, because this is the first
+	  and only layer that will always exist in our maps. Users aren't able to
+	  remove it!
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapThemePanel.java:
+	  Added a callback interface that allows the MapOutputTab to react on
+	  modifications in the ThemePanel. This special callback is used to
+	  activate/deactivate layers.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Now, the layers in the map reflect the facets of the map output. Each
+	  layer's extent is analyzed and finally the map is zoomed to the minimal
+	  extent that contains all layers.
+
+2011-07-20  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ThemeNavigationPanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/ThemeNavigationPanel.java:
+	  Moved the panel a package level higher.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ThemePanel.java: New.
+	  Abstract class that consists basically of the code that was removed from
+	  ChartThemePanel.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartThemePanel.java:
+	  Sourced code base out to ThemePanel, so that's possible to reuse the
+	  code for a MapThemePanel.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapThemePanel.java:
+	  New. A theme panel for the map widget.
+
+2011-07-19  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/AttributedTheme.java:
+	  New. This theme stores all its attributes in a map. The intent of this
+	  theme is to save all the facet's values contained in the DESCRIBE of the
+	  Collection to be able to write an equivalent attribute part as the
+	  incoming DESCRIBE has -> no loss of attributes like WMS URL or
+	  layernames in a map theme!
+
+	* src/main/java/de/intevation/flys/client/server/DescribeCollectionServiceImpl.java:
+	  Instantiate new AttributedThemes to save all information of a facet.
+
+	* src/main/java/de/intevation/flys/client/server/CollectionHelper.java:
+	  Write all attributes of an AttributedTheme into a facet's element.
+
+	* src/main/java/de/intevation/flys/client/shared/model/Theme.java,

+	  src/main/java/de/intevation/flys/client/client/ui/chart/ChartThemePanel.java:
+	  The 'active' member variable is an integer value now as it is in the
+	  Collection's DESCRIBE document, too.
+
+2011-07-18  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/services/ArtifactServiceAsync.java,
+	  src/main/java/de/intevation/flys/client/client/services/ArtifactService.java,
+	  src/main/java/de/intevation/flys/client/server/ArtifactServiceImpl.java:
+	  An artifact can be created using a UUID as model artifact.
+
+	* src/main/java/de/intevation/flys/client/server/ArtifactDescriptionFactory.java:
+	  Read artifact recommendations from artifact description.
+
+	* src/main/java/de/intevation/flys/client/shared/model/ArtifactDescription.java,
+	  src/main/java/de/intevation/flys/client/shared/model/DefaultArtifactDescription.java:

+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java,
+	  src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  Adapted the call of the ArtifactService.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  If the Artifact of a collection changes, the recommended Artifacts - if
+	  existing - are created and added to the current Collection.
+
+2011-07-12  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MeasureControl.java:
+	  New. This control consists of two OpenLayers controls to measure lines
+	  and polygons.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapToolbar.java:
+	  Added the MeasureControl.
+
+	* src/main/webapp/images/measurePolygon.png,
+	  src/main/webapp/images/measurePolygon_Selected.png,
+	  src/main/webapp/images/measureLine.png,

+
+2011-07-12  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapPositionPanel.java:
+	  New. This panel displays the mouse position in map coordinates.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/DrawControl.java::
+	  New. This control consists of a button to enable the control and a
+	  combobox that provides different types of barriers. Dependent on the
+	  selected barrier type, the user can draw lines or polygons into the map.
+
+	* src/main/java/de/intevation/flys/client/client/utils/EnableDisableCmd.java:
+	  New. This interface might be used to react on enable/disable operations.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapToolbar.java:
+	  Added controls to digitize lines and polygons.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/FloodMap.java:
+	  Added a method that returns a vector layer that might be used to insert
+	  new barriers draw by the user. This layer is used by the DrawControl.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  The MapToolbar requires a Canvas object now, which is used to keep track
+	  on the current mouse position.
+
+	* src/main/webapp/images/selectFeature_Selected.png,
+	  src/main/webapp/images/selectFeature.png,
+	  src/main/webapp/images/digitize.png,
+	  src/main/webapp/images/digitize_Selected.png,
+	  src/main/webapp/images/removeFeature.png: New. Icons for the map control

+
+2011-07-11  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapToolbar.java:
+	  New. This toolbar provides controls that interact with the map.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/FloodMap.java:
+	  Removed the initialization of map controls.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Added the MapToolbar at the top of the layout.
+
+2011-07-11  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Finished layouting the components. The map has the same layout as the
+	  chart now.
+
+2011-07-08  Ingo Weinzierl <ingo@intevation.de>
+
+	* pom.xml: Added a dependency to GwtOpenLayers 0.5 (Apache 2.0).
+
+	* src/main/java/de/intevation/flys/client/FLYS.gwt.xml: Include the GWT
+	  OpenLayers code.
+
+	* src/main/webapp/FLYS.html: Include OpenLayers 2.9 (currently from remote
+	  openlayers.org server). For production use, we have to include a local
+	  OpenLayers.
+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: Small
+	  modification on the way to render the HTML page. This lets us now
+	  combine GWT and SmartGWT components.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/FloodMap.java:
+	  New. This components manages the map provided by GwtOpenLayers.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Initializes a FloodMap now and renders the map in the middle area. Note,
+	  that the layout is nearly completely using GWT components. Mixing
+	  GwtOpenLayers with SmartGWT doesn't work here.
+
+2011-07-08  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/OutputMode.java: An
+	  output mode has type member now. In addition, the interface describes a
+	  method that creates an OutputTab. Concrete subclasses should return
+	  OutputTabs that fit to their type.
+
+	* src/main/java/de/intevation/flys/client/shared/model/ChartMode.java:
+	  New. This OutputMode is instantiated if type == "chart" and creates
+	  ChartOutputTabs.
+
+	* src/main/java/de/intevation/flys/client/shared/model/MapMode.java: New.
+	  This OutputMode is instantiated if type == "map". It creates
+	  MapOutputTabs.
+
+	* src/main/java/de/intevation/flys/client/shared/model/DefaultOutputMode.java:
+	  This default implementation of an OutputMode support the type member
+	  now. The method to create OutputTabs will return null.
+
+	* src/main/java/de/intevation/flys/client/server/DescribeCollectionServiceImpl.java:
+	  Now, we support the 'type' attribute of Outputs in the DESCRIBE
+	  document. Based on the type, we will now instantiate concrete subclasses
+	  of the DefaultOutputMode. E.g. the type == 'chart', the instantiated
+	  OutputMode will be ChartMode.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  New. This OutputTab is used to render a map.
+
+	  Note: This is currently a stub only!
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Creating OutputTabs based on the names of an OutputMode is obsolete.
+	  Now, the OutputModes itself create their required OutputTab.
+
+2011-07-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,

+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java:
+	  Added strings for the output mode 'floodmap'.
+
+2011-07-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/BooleanPanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/TextProvider.java,
+	  src/main/java/de/intevation/flys/client/client/ui/AutoIntegerPanel.java:
+	  Default values provided by the data list used to create the panels are
+	  set now.
+
+2011-07-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java:
+	  Refactored getting labels out to own methods which enables subclasses to
+	  changed them.
+
+	* src/main/java/de/intevation/flys/client/client/ui/WaterlevelGroundPanel.java:
+	  Override methods of DistancePanel to support own labels for this panel.
+	  In addition, this panel has no distance/locations table as the
+	  DistancePanel has.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_en.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java: Added
+	  new strings for the distance panel and the waterlevel/ground panel.
+
+2011-07-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/BooleanPanel.java:
+	  This panel is a sublcass of TextProvider now. The difference to the
+	  TextProvider is, that there is the option to active/deactivate a
+	  checkbox. So, the valid values returned by this panel are "true" and
+	  "false".
+
+2011-07-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/TextProvider.java:
+	  Made methods in this class much smaller to override them easily in
+	  subclasses. In addition, the TextItem has been replaced with a
+	  DataSourceField which seems to be more easily to change in subclasses.
+
+	* src/main/java/de/intevation/flys/client/client/ui/AutoIntegerPanel.java:
+	  Override required methods of TextProvider. This panel now accepts
+	  integer values and the string "auto". An inner class
+	  AutoIntegerValidator is used to validate the user input.
+
+	* src/main/webapp/FLYS.css: Set style for html label elements. Those label
+	  elements are used in forms to label items.
+
+2011-07-06  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/event/ParameterChangeEvent.java:
+	  This event now supports a further member variable "type". Type is an
+	  enum and can be FORWARD or BACK which reflects to stepping forward or
+	  backward with the master artifact.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  Improved the way of adding/removing items to/from the static list of
+	  parameters. We now distinguish between the two ways:
+	  - step forward: the last item in the list is added to the static
+	                  parameter list. This makes redrawing much smoother.
+	  - step backward: only the necessary items are removed from the static
+	                   parameter list. Before, we have removed all items and
+	                   added the relevant ones afterwards. This makes
+	                   redrawing also much smoother.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ContinuePanel.java:
+	  This panel will have no static widget.
+
+	* src/main/java/de/intevation/flys/client/client/ui/AutoIntegerPanel.java:
+	  This panel uses the parents createOld() now.
+
+2011-07-06  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java,
+	  src/main/webapp/FLYS.css: Some layout improvements related to the height
+	  of components.
+
+2011-07-06  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  The right side of the ParameterList now consists of a stacked panel that
+	  itself consists of the helper panel and a panel for displaying the
+	  calculation results. The user is now able to see both at the same time.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Improved the Collection update process. There is no need to update the
+	  collection twice when the master artifact changed. Now, the collection
+	  is updated only a single time if the collection itself changed - and it
+	  changes everytime when its artifact is set.
+
+	* src/main/java/de/intevation/flys/client/client/ui/TableDataPanel.java:
+	  The label 'Berechnungsergebnisse' is no longer part of the Canvas
+	  created by this class.
+
+	* src/main/java/de/intevation/flys/client/client/ui/UIProvider.java,
+	  src/main/java/de/intevation/flys/client/client/ui/AbstractUIProvider.java:
+	  The helper panel is now a VLayout, no longer a Canvas.
+
+	* src/main/java/de/intevation/flys/client/client/ui/LocationDistancePanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/MapSelection.java,
+	  src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/SingleLocationPanel.java:

+
+2011-07-05  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/DoubleRangePanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java:
+	  Modified these classes with the intent to override them easier.

+	  New panels for data input. The work on these classes is not finished
+	  yet!
+
+	* src/main/java/de/intevation/flys/client/client/ui/UIProviderFactory.java:
+	  Support more UI providers that return the new panels above.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java: New

+
+2011-07-05  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/event/AdvanceHandler.java:
+	  New. This interface describes a handler that listens to events in order
+	  to advance to a next step.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ContinuePanel.java:
+	  New. This panel doesn't allow users to enter data. It only displays a
+	  link that lets users step forward to a next state.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  The ParameterList needs to take care on states that do not require user
+	  input but that aren't the final state of an artifact. In such case, the
+	  UI provider should be the ContinuePanel only! It allows users to step to
+	  the next state. In order to provide such functionality - step forward
+	  without feeding the artifact - the ParameterList now implements the
+	  AdvanceHandler.
+
+	* src/main/java/de/intevation/flys/client/client/ui/UIProviderFactory.java:
+	  If the uiprovider attribute is 'continue', the ContinuePanel is
+	  returned.
+
+	* src/main/java/de/intevation/flys/client/client/ui/SelectProvider.java:
+	  Adapted the width of the label field.

+
+	* src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java:
+	  Connected columns of the locations and distances tables with the
+	  panels from/to fields. The first two columns of the locations and the
+	  first column of the distances table might be used to set from/to values
+	  in the panel.
+
+2011-07-01  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/DistanceInfoXML.java:
+	  New. This service - which is no GWT RPC Service - returns the distance
+	  info document as XML. The content of the document is not modified,
+	  parsed but only copied through.
+
+	* src/main/java/de/intevation/flys/client/client/ui/range/DistanceInfoDataSource.java:
+	  New. This data source is used to fill the LocationsTable and RangeTable.
+	  It uses the DistanceInfoXML service to query the required data
+	  automatically using a "locations" or "distances" filter to reduce the
+	  size of the data document.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java:
+	  Use the DistanceInfoDataSource to fill the locations and distances tables.
+
+	* src/main/webapp/WEB-INF/web.xml: Registered the new service.
+
+2011-06-30  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/range/LocationsTable.java,
+	  src/main/java/de/intevation/flys/client/client/ui/range/RangeTable.java:
+	  New. These two tables are used to support the user to select from/to
+	  values in the distance panel.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java:
+	  Added LocationsTable and RangeTable that currently load no data.
+
+2011-06-30  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java:
+	  New. This panel is used to insert kilometer ranges. There is no input
+	  mode for locations as it is in LocationDistancePanel.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants_en.properties,

+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java:
+	  Added i18n strings for the distance panel.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DoubleRangePanel.java:
+	  Added a method to set the step width.
+
+	* src/main/java/de/intevation/flys/client/client/ui/UIProviderFactory.java:
+	  Create a DistancePanel UIProvider if the "uiprovider" string in the
+	  DESCRIBE of an artifact equals "distance_panel".

+	  Create the chart image first before initialising listeners on it.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ZoomboxControl.java:
+	  The zoombox that is displayed in while zooming is 2 pixel smaller than
+	  the area between start and end point now. This should avoid the zoombox
+	  absorbing mouse events.
+
+2011-06-29	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

+	  We will no longer check if an update of the theme list is necessary.
+	  The EditEvent that is caught should be enough information to start the

+	  flys/issue165 (Projektliste: Einige Auffälligkeiten nach Neuimplementierung)
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  Set the maximal length of project names to 50 characters. If the name,
+	  entered by the user, is longer than this max value, it is not saved to
+	  artifact server and the old name is displayed again.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_en.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,

+	  Added warning message for too long project names.
+
+2011-06-24  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  The "zoom-to-max-extent" button will have the effect that no zoom values
+	  are transfered to the server.
+
+2011-06-24  Ingo Weinzierl <ingo@intevation.de>
+
+	  flys/issue21 (Gleiches Projekt kann mehr als einmal gleichzeitig geöffnet werden)
+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: Implements
+	  CollectionChangeHandler to lock new projects. In addition, there is a
+	  new method to close projects.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  If this view contains a Collection, FLYS is used to close this window.
+	  FLYS needs to unlock the project before the view is destroyed.
+	  Otherwise - if no Collection has been created yet - this view destroys
+	  itself.
+
+2011-06-23  Ingo Weinzierl <ingo@intevation.de>
+
+	  flys/issue170 (Diagramm: Initiales Zoomen zeigt verschobenen Bereich)
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  The chart image is no longer removed from DOM but it's source is set to
+	  a new value after the panel's size changes. This makes the zoom actions
+	  much smoother and there the initial zoom values are no longer broken.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/PanControl.java:
+	  Panning will now move the image itself but not its parent element.
+
+	* src/main/java/de/intevation/flys/client/shared/model/ChartInfo.java,
+	  src/main/java/de/intevation/flys/client/shared/Transform2D.java: Added

+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: Added a
+	  handler that catches uncaught exceptions. Those exceptions are displayed
+	  using a new method showWarning(Throwable t). This method brings up a
+	  Window that displays the stacktrace of the exceptions.
+
+2011-06-23	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

+
+2011-06-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Register the CollectionView when a new collection is created. This is
+	  necessary to avoid an inconsistent view that would otherwise display
+	  projects that might have been deleted.
+
+2011-06-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:

+
+	  TODO: We still need to write RPC services to update those values!
+
+2011-06-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties:

+	  now. This value is retrievable via getTTL().
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  The project list has now a column that displays an icon that shows the

+	  effect except it brings up the project window.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:

+	  The Transform2D object is included in this new ChartInfo.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  Implements the PanHandler interface. If a PanEvent is fired by the

+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:

+	  New method to reset the zoom.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartToolbar.java:
+	  Added a button that resets the zoom and triggers an update of the chart.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ZoomboxControl.java:
+	  This control inherits from ImgButton now. The icon displayed for this
+	  control is the same as in the desktop version of this software.

+2011-06-03  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/ChartOutputServiceImpl.java:
+	  Append the selected min and max ranges for x and y axes to the attribute
+	  document. This enables the server to zoom the chart to the specified
+	  view.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  The x and y ranges specified after zooming are stored as instance
+	  variables and used while creating the chart imgage url. The
+	  ChartOutputService will put those ranges into the attribute document for
+	  the chart creation.
+
+2011-06-01  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  Implements the ZoomHandler interface now. Currently, the values are just
+	  received from ZoomboxControl. We still need to refresh the chart with
+	  those zoom values.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartToolbar.java:
+	  Registered the ChartOutputTab as ZoomHandler at the ZoomboxControl.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ZoomboxControl.java:
+	  Bugfix: fire the ZoomEvent when mouse up events occur. The events was
+	  not fired anytime.

+	* src/main/java/de/intevation/flys/client/client/ui/chart/ZoomboxControl.java:
+	  New. A zoombox control that draws - if activated - an semi opaque
+	  rectangle on the top of the observed panel. This control uses mouse
+	  up/down/move events to draw the rectangle. A mouse down event starts the
+	  zoom process, a mouse up event determines the coordinates for the zoom
+	  and fires a ZoomEvent.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartToolbar.java:
+	  Added the ZoomboxControl.
+
+2011-06-01  Ingo Weinzierl <ingo@intevation.de>

+	  now. The components inside this panel have also fixed width values.
+
+2011-06-01  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  After the chart panel is resized, we will now fetch a chart info
+	  document using the ChartInfoService. This service lets us update the
+	  current Transform2D - which is used to display mouse position in chart
+	  coordinates and determine mouse clicks for zooming.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartToolbar.java:
+	  Changed the constructor call of the MousePositionPanel. It needs to
+	  ChartOutputTab now.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/MousePositionPanel.java:
+	  Changed the way to compute the chart coordinates. We will now use the
+	  Transform2D object that is returned by the ChartInfoService.
+
+2011-06-01  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:

+	  src/main/java/de/intevation/flys/client/client/services/ChartInfoService.java,
+	  src/main/java/de/intevation/flys/client/server/ChartInfoServiceImpl.java:
+	  New. A service that fetches the chart info document provided by the
+	  artifact server and returns (currently) a Transform2D object.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_en.properties,

+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartToolbar.java:
+	  Added the MousePositionPanel.
+
+	  NOTE: The MousePositionPanel does NOT show the correct position and it
+	  does NOT show the x|y coordinates in chart dimension yet!
+
+2011-05-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:

+	  src/main/java/de/intevation/flys/client/client/event/OutputParameterChangeHandler.java,
+	  src/main/java/de/intevation/flys/client/client/event/OutputParameterChangeEvent.java:
+	  Interface and class to realize a listener mechanism for output parameter
+	  changes.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartThemePanel.java:
+	  Implements the OutputParameterChangeHandler interface. After the output
+	  parameter of the chart have changed, the chart is refreshed.
+
+	  NOTE: The panel is disabled right before the RPC call to replace the
+	  collection's attribute is executed. It is enabled after the RPC call has
+	  finished.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  Implements the HasOutputParameterChangeHanders interface. The event is
+	  fired if there are changes in the chart theme control panel.
+
+2011-05-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/CollectionAttributeServiceImpl.java:

+	  Collection will be stored in the artifact database now.
+
+	* src/main/java/de/intevation/flys/client/server/CollectionHelper.java:
+	  New. This helper is currently used to create the attribute document of a
+	  collection based on a Collection itself. This helper now takes the
+	  attributes of the Collection and transforms those values into XML.
+
+2011-05-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/Theme.java,

+	  the new position, all other themes in this list are moved up or down.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartThemePanel.java:
+	  The actions in the navigation panel have now an effect on the order of

+	  src/main/java/de/intevation/flys/client/server/CollectionAttributeServiceImpl.java:
+	  New. This service should be used to modify/update the attribute of a
+	  collection.
+
+	  NOTE: The update process needs to be implemented! Currently, the only
+	  thing this service does is, that is waits 5sec and fetches a new
+	  description right after this ;-)
+
+	* src/main/java/de/intevation/flys/client/shared/model/ThemeList.java:
+	  Added methods to remove and add themes.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartThemePanel.java:

+	  artifact this theme belongs to.
+
+	* src/main/java/de/intevation/flys/client/shared/model/ThemeList.java:
+	  New. A ThemeList is a wrapper for themes and should provide some

+2011-03-30  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  Removed some comments that have been commited by mistaken.
+
+2011-03-30  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages.java:
+	  Derives the ConstantsWithLookup interface now. This makes it possible to
+	  fetch i18n string using a getString(String key) lookup method.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages_en.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSMessages_de.properties:
+	  Removed '@DefaultMessage' annotations - they are not available for
+	  ConstantsWithLookup, added a further i18n string and fixed another one.
+
+	* src/main/java/de/intevation/flys/client/client/ui/MainMenu.java,
+	  src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Some modifications related to the changes above.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  Removed the hard coded title determination based on the selected module.
+	  Now, the getString() of FLYSMessages is used to determine the human
+	  readable string.
+

+
+	* src/main/java/de/intevation/flys/client/server/DescribeCollectionServiceImpl.java,
+	  src/main/java/de/intevation/flys/client/server/AddArtifactServiceImpl.java,
+	  src/main/java/de/intevation/flys/client/client/services/DescribeCollectionService.java,
+	  src/main/java/de/intevation/flys/client/client/FLYS.java,
+	  src/main/java/de/intevation/flys/client/client/ui/LocationDistancePanel.java,

+	  src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/SelectProvider.java,
+	  src/main/java/de/intevation/flys/client/client/ui/FLYSFooter.java:
+	  Removed useless imports.
+
+2011-03-29  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: The
+	  CollectionView no longer gets an empty collection when it is created.
+
+	* src/main/java/de/intevation/flys/client/client/ui/FLYSWorkspace.java:
+	  The CollectionViews are no longer stored in a Map but in a List.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Bugfix: We just create a new collection a single time - if no one is
+	  existing. If the output modes of the artifact that is used for the
+	  parameterization changes, we fetch the new DESCRIBE document of the
+	  collection using the new DescribeCollectionService.
+
+2011-03-29  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/DescribeCollectionServiceImpl.java,
+	  src/main/java/de/intevation/flys/client/client/services/DescribeCollectionServiceAsync.java,
+	  src/main/java/de/intevation/flys/client/client/services/DescribeCollectionService.java:
+	  New. This service is used to fetch the DESCRIBE document of a specific
+	  collection and returns a Collection object that contains the information of
+	  that document. The code to parse the DESCRIBE has been moved here from
+	  the AddArtifactServiceImpl which now derives the
+	  DescribeCollectionServiceImpl.
+
+	* src/main/java/de/intevation/flys/client/server/AddArtifactServiceImpl.java:
+	  This service is derived from DescribeCollectionServiceImpl now, because
+	  the methods to parse the DESCRIBE document are moved to that service.
+
+	* src/main/webapp/WEB-INF/web.xml: Registered the
+	  DescribeCollectionService.
+
+2011-03-29  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages_de.properties:
+	  Replaced the german title of the project list 'Berechnungen' with
+	  'Projekte'.
+
+2011-03-29  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: Registered the
+	  ProjectList as CollectionChangeHandler of each created CollectionView.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  Implements the CollectionChangeHandler to update the list of user
+	  collections after a collection changed (or has been created).
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionGrid.java,
+	  src/main/java/de/intevation/flys/client/shared/model/CollectionRecord.java:
+	  Modified the output of the 'name' and 'date' fields.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages_en.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSMessages_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSMessages.java:
+	  Added a format for datetime strings.
+
+2011-03-29  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/UserCollectionsServiceImpl.java,
+	  src/main/java/de/intevation/flys/client/client/services/UserCollectionsServiceAsync.java,
+	  src/main/java/de/intevation/flys/client/client/services/UserCollectionsService.java:
+	  New. This service returns a list of Collections owned by a specified
+	  user.
+
+	* src/main/webapp/WEB-INF/web.xml: Registered the UserCollectionsService.
+
+2011-03-29  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/DefaultCollection.java,
+	  src/main/java/de/intevation/flys/client/shared/model/Collection.java:
+	  Added methods to retrieve the creation time.
+
+2011-03-29  Raimund Renkert <rrenkert@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/MainMenu.java: Fixed code
+	  in ProjectList toggle method.
+
+	* src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java: Fixed
+	  the WQInputPanel label to have the correct size.
+
+2011-03-29  Raimund Renkert <rrenkert@intevation.de>
+
+	* src/main/webapp/FLYS.html: Added style information to avoid the smartgwt
+	  theme margin.
+
+2011-03-29  Raimund Renkert <rrenkert@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages_de.properties:
+	  Changed some german strings.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Changed tab title.
+
+2011-03-29  Raimund Renkert <rrenkert@intevation.de>

+	  src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/SelectProvider.java: Set
+	  label width to have a tabled style for WINFO selections.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Resized window to fit the content size.
+
+2011-03-29  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  The ParameterList is a Tab now and can set its title itself. So, the
+	  title will change after the module is chosen.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Removed code to insert the ParameterList into a new Tab. This is no longer
+	  needed, because the ParameterList is a Tab itself.
+
+2011-03-29  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages_en.properties,

+
+	* src/main/java/de/intevation/flys/client/client/ui/AbstractUIProvider.java:
+	  Modified the URL that points to the 'back button' image. Now, the
+	  base URL is taken into account as well. The button will be shown
+	  everywhere now (in every installation)!
+
+2011-03-29  Raimund Renkert <rrenkert@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/LocationDistancePanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/SelectProvider.java: Set
+	  label width to have a tabled style for WINFO selections.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:

+
+2011-03-29  Raimund Renkert <rrenkert@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/MainMenu.java: Fixed
+	 toggle method.
+
+2011-03-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/CollectionItem.java,
+	  src/main/java/de/intevation/flys/client/shared/model/DefaultCollectionItem.java:
+	  A CollectionItem has a hash() method now. The value comes from the
+	  Collection's DESCRIBE document.
+
+	* src/main/java/de/intevation/flys/client/server/AddArtifactServiceImpl.java:
+	  The hash value of a collection item is parsed from DESCRIBE document.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ChartOutputTab.java:
+	  Appended the hash value of the artifact to the URL of the chart image.
+	  This bypasses the browser cache of a previous chart image.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  A parameterization change will always remove all output tabs before
+	  updating the output tab panel.
+
+2011-03-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages_en.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSMessages_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSMessages.java:
+	  Modified existing string and added a new one.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ModuleSelection.java:
+	  Added a further radio button for a plugin and changed the alignment of
+	  the radio button to vertical.
+
+2011-03-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ChartOutputTab.java:
+	  Removed the "TODO: ThemeEditor" label.
+
+2011-03-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Removed the date string from title bar.
+
+2011-03-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/UIProvider.java,
+	  src/main/java/de/intevation/flys/client/client/ui/AbstractUIProvider.java:
+	  A UIProvider might now have a panel that can be used to render helper
+	  widgets. E.g. the river selection will render its river map into this
+	  panel. It is injected and can be placed somewhere around the
+	  application.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  Injected the right panel of the parameter panel into the UIProvider.
+	  Helper widgets are rendered into this panel now!
+
+	* src/main/java/de/intevation/flys/client/client/ui/LocationDistancePanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/MapSelection.java,
+	  src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/SelectProvider.java,
+	  src/main/java/de/intevation/flys/client/client/ui/ModuleSelection.java:
+	  Some layout improvements (heights, position of elements and so far).
+
+2011-03-28  Raimund Renkert <rrenkert@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/MainMenu.java: The project
+	list button toggles the project list now.
+
+2011-03-28  Raimund Renkert <rrenkert@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/AbstractUIProvider.java:
+	  Replaced next button image with smartgwt button.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages.java: Removed
+	 button path, added text for new button.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages_en.properties:

+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages_de.properties:
+	  Removed image path, added german text for button.
+
+2011-03-28  Raimund Renkert <rrenkert@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages.java: Added text
+	  for FLYSFooter.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages_de.properties:
+	  Added german text for footer label.
+
+	* src/main/java/de/intevation/flys/client/client/ui/FLYSFooter.java: New. A
+	  new ui element at the bottom of the page.
+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: Added footer
+	  element to FLYS webpage.
+
+2011-03-28  Raimund Renkert <rrenkert@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  Customized ProjectList style.
+	* src/main/java/de/intevation/flys/client/client/ui/FLYSView.java: Set
+	  background color and size constraints.
+
+	* src/main/webapp/FLYS.css: Added background style.
+
+2011-03-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ChartOutputTab.java:
+	  The right side of this panel displays an image now. This image
+	  represents a chart that is generated by an artifact. The request is made
+	  up in the ChartOutputServiceImpl.
+
+	* src/main/java/de/intevation/flys/client/server/ChartOutputServiceImpl.java:
+	  New. This service creates the request to retrieve chart images and
+	  writes the response to the output stream.
+
+	  NOTE: This service is not asynchron! It is derived directly from
+	  HttpServlet.
+
+	* src/main/webapp/WEB-INF/web.xml: Registered the ChartOutputService.
+
+2011-03-25  Raimund Renkert <rrenkert@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Limited the area for CollectionView to the size of FLYSWorkspace.
+
+2011-03-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/OutputTab.java: Fixed
+	  a typo.
+
+2011-03-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ChartOutputTab.java:
+	  An OutputTab with two panels. The left one is not implemented yet
+	  (ThemeEditor). The right one will display an image.
+
+	* src/main/java/de/intevation/flys/client/client/ui/OutputTab.java: The
+	  content pane is set in the constructor.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  New output tabs will use the ChartOutputTab.
+
+	  NOTE: We should move the code that constructs the concrete output tabs
+	  into a factory class that decides which OutputTab has to be used.
+
+2011-03-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  The tab bar is extended with output tabs if the artifact used for the
+	  parameterization reaches a state with output modes.
+
+	* src/main/java/de/intevation/flys/client/client/ui/OutputTab.java: A
+	  base class that might be used to derive concrete output tabs for charts,
+	  maps and so on.
+
+2011-03-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java,
+	  src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  Moved parameterization specific code from CollectionView to
+	  ParameterList.
+
+2011-03-26  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java,
+	  src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  Moved ParameterList specific code into the ParameterList.
+
+2011-03-25  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/services/CreateCollectionService.java,
+	  src/main/java/de/intevation/flys/client/client/services/CreateCollectionServiceAsync.java,
+	  src/main/java/de/intevation/flys/client/server/CreateCollectionServiceImpl.java:
+	  Changed the return type to 'Collection' - returned a UUID (String)
+	  before.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  The artifact is put into the collection (or new collection) if we reach
+	  a step in the parameterization in that an artifact has reachable
+	  outputs. Furthermore, some adjustments related to the changes of the
+	  return type in the CreateCollectionService.
+
+2011-03-25  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/webapp/WEB-INF/web.xml: Made the AddArtifactService accessible.
+
+2011-03-25  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/services/AddArtifactServiceAsync.java,
+	  src/main/java/de/intevation/flys/client/client/services/AddArtifactService.java,
+	  src/main/java/de/intevation/flys/client/server/AddArtifactServiceImpl.java:
+	  New. This service adds an existing artifact to an existing collection.
+	  The return value of this service is a Collection that is filled with
+	  CollectionItems and OutputModes.
+
+2011-03-25  Raimund Renkert <rrenkert@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/FLYS.gwt.xml: Changed theme to
+	  smartgwt Enterprise Blue.
+
+2011-03-25  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/Facet.java,
+	  src/main/java/de/intevation/flys/client/shared/model/DefaultFacet.java:
+	  New. An interface and its default implementation that provide methods
+	  to get information about facets. Currently, the only information that is
+	  supported is the name of the facet.
+
+	* src/main/java/de/intevation/flys/client/shared/model/CollectionItem.java,
+	  src/main/java/de/intevation/flys/client/shared/model/DefaultCollectionItem.java:
+	  New. An interface and its default implementation that provide methods to
+	  get information about the available output modes and its facets of
+	  artifacts -> a CollectionItem is related to an artifact - both have the
+	  same identifier.
+
+	* src/main/java/de/intevation/flys/client/shared/model/DefaultCollection.java,
+	  src/main/java/de/intevation/flys/client/shared/model/Collection.java:
+	  The Collection no longer stores references to artifacts, but to
+	  CollectionItems. I have changed this, because the artifact contains a
+	  lot more information we need for the Collections. So, I decided to
+	  create CollectionItems that are related to artiacts but just know about
+	  the possible outputmodes and facets.
+
+2011-03-24  Raimund Renkert <rrenkert@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/MainMenu.java: Set styles
+	  for label.
+
+	* src/main/java/de/intevation/flys/client/client/ui/FLYSHeader.java: Fixed the
+	  method to calculate the image width and resized the BfG logo.
+
+	* src/main/webapp/FLYS.css: Introduced styles for fonts and BfG colorscheme.
+
+2011-03-23  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/ArtifactDescriptionFactory.java:
+	  Extract the output modes from DESCRIBE document and fill the
+	  ArtifactDescription with those objects.
+
+2011-03-23  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/ArtifactDescription.java:
+	  Added a method to retrieve the available output modes of the artifact.
+
+	* src/main/java/de/intevation/flys/client/shared/model/DefaultArtifactDescription.java:
+	  Implemented the method to retrieve the available output modes and
+	  enhanced the default constructor with a parameter for output modes.
+
+2011-03-23  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/OutputMode.java,
+	  src/main/java/de/intevation/flys/client/shared/model/DefaultOutputMode.java:
+	  New. An interface and its default implementation that describes
+	  available output modes of artifacts.
+
+2011-03-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/webapp/images/next.xcf: Moved to images/next.xcf to avoid that
+	  this file is included in the WAR archive of the web application.
+
+	* images/next.xcf: Moved from src/main/webapp/images/next.xcf.
+
+2011-03-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/ArtifactDescriptionFactory.java:
+	  Parse the selected values as human readable strings from the static UI
+	  part.
+
+	* src/main/java/de/intevation/flys/client/client/ui/SelectProvider.java:
+	  Display human readable values in the static UI part.
+
+2011-03-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/event/HasStepBackHandlers.java,
+	  src/main/java/de/intevation/flys/client/client/event/StepBackHandler.java,
+	  src/main/java/de/intevation/flys/client/client/event/StepBackEvent.java:
+	  New. These classes are used to realize a notification mechanism to
+	  listen to the step-back part of the advance() operation. UI elements
+	  should fire a StepBackEvent if the user tries to step back to a previous
+	  state.
+
+	* src/main/java/de/intevation/flys/client/client/ui/AbstractUIProvider.java:
+	  The UIProvider implements the HasStepBackHandlers interface and fires
+	  StepBackEvents if the 'back' button has been clicked.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  Listens to StepBackEvents. If such an event is received, we gonna remove
+	  all old state items from the list and revert the view. Afterwards, the
+	  artifact description is used to redraw the whole view.
+
+	  NOTE: I think we should just remove those items that belong to states
+	  between the current state and the target state. This would avoid a
+	  complete refresh of the ParameterPanel.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Listens to StepBackEvents. If such an event is received, the advance()
+	  operation is triggerd with the current artifact and the new target
+	  state identifier to step back to that state.
+
+2011-03-18  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/DoubleRangePanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/DoubleArrayPanel.java:

+	  validation.
+
+	* src/main/java/de/intevation/flys/client/client/ui/LocationDistancePanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java:
+	  Added a mechanism to validate and save user input before returning the
+	  data entered in the fields.
+	  Reason: the BlurEvent - after that we gonne validate and save the input
+	  stuff - is not fired when the focus is still in one of the text fields
+	  and we click the 'next' button immediately. A nullpointer exception
+	  would be the result (which is avoided with the mechanism).

+	  widget that stores and displays the data of former states and the current
+	  data. The widget displaying of the current data is created by the
+	  UIProvider that is stored in the Data object.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java: We
+	  are able to create new WINFO artifacts. After the artifact has been
+	  created, the first 'state' is rendered in a 'WINFO tab' using the

+== Version 2.4.0 (27.06.2011, rev. 2257) ==
+
+Diese Seite stellt primär Neuerungen in dieser Version aus Sicht des Nutzers zusammen bzw. verweist auf Vorarbeiten, die für jeweilige Funktionen benötigt werden.
+
+=== Zusammenfassung und Hintergedanken zur Version ===
+Die Version 2.4 verfolgt für WINFO das Ziel die fachliche Nachprüfbarkeit der bestehenden Berechnungsarten bereitzustellen. Hierbei sind folgende Aspekte wichtig:
+ * fachliche Richtigkeit und Genauigkeit der bestehenden Berechnungsarten
+ * Bereitstellung und Unterstützung eines Berichtswesens in den Berechnungsvorgängen
+ * Vorbereitung der Berechnungsarten für den Mehrbenutzerbetrieb
+ * Vollständigkeit der benötigten Fachdaten aus dem FLYS-Datei-Server für bestehende Funktionen (Kantenbilder, Typisierung Streckenfavoriten)
+ * Export aller benötigten Berechnungsdaten in entsprechenden Formaten (WST, WST korrigiert, CSV, AT)
+
+Um diese Ergebnisse visualisieren und im konsolidierten Diagrammbereich testen zu können, stellt das Diagramm die zentralen interaktiven Funktionen zur Navigation und Themensteuerung bereit und prüft die Kopplung von Client und Server Zusammenspiel. Um dem Nutzer die Verbindung seines Gesamtworkflows zu ermöglichen, ist die Projektverwaltung mit interaktiven Funktionen ausgestattet worden. Diese setzt unterschiedliche Parameterisierungen und Darstellungen in Projekten in Zusammenhang.

+ 
+
+2011-05-16  Release V 2.3.0
+
+=== Framework ===
+
+ * Projektverwaltung (Pflichtenheft Kap. 3.3, Lokale Daten > Arbeitssitzungen)
+  * Mit dem Anlegen eines neuen Projektes wird die Projektliste automatisch gefüllt.
+   * Zu beachten: Zur Zeit operiert das System noch mit '''einem''' Benutzer, so dass jeder alle auf dem Server liegenden Projekte sieht. Mit der Einführung einer Nutzeranmeldung sieht dann jeder Nutzer nur noch seine eigenen Projekte.
+  * Mit einem Doppelklick oder das Kontextmenü können die jeweiligen Projekte wieder geöffnet werden. Sie stellen den Arbeitszustand des letzten "Übernehmen" wieder her. Die Einstellung ist sprachunabhängig, d.h. auch wenn zuvor Diagramme in deutsch erstellt worden sind, können diese in englischer Sprache geöffnet und dargestellt werden.
+   * Projekte können Projekte noch in mehreren Fenster geöffnet werden. Um Konsistenz herzustellen, kann man ein Projekt nur einmal öffnen. (vgl. https://roundup-intern.intevation.de/flys/issue21)
+  * Neue Fenster überlappen sich nicht mit der Position des vorherigen Fensters, um beim Anlegen eines neuen Projektes eine vollständige Überdeckung zu vermeiden
+   * Projektfenster maximieren (vgl. https://roundup-intern.intevation.de/flys/issue35)
+
+ * Projekteinstieg
+  * Klick-Optimierung der Gewässerauswahl über eine Liste: von 3 Klicks zu 1 Klick.
+
+ * Internationalisierung (Pflichtenheft, Kap.4.3.4)
+  * Beim Start wird die Spracheinstellung des Browser automatisch ausgewertet und die dazugehörige Oberfläche in deutsch oder englisch geladen. Wenn eine andere Sprache als deutsch oder englisch angefragt wird, fällt die Anwendung auf englisch (TOCHECK) zurück.
+  * Die Sprache kann jeweils manuell gewechselt werden. Dies hat Auswirkungen auf die Bedienoberfläche, Diagramme und Nutzung von Dezimaltrenner und Punkt
+
+=== Fachdatenbestand ===
+ * Import der hydrologischen Daten der Elbe
+##  * Was wird nicht berücksichtigt?
+##   * Spalten in wst-Dateien mit einer - Notation; andere, nicht einheitliche werde jeweils mit einer Ziffer erweitert
+ * Einige Zahlen zum Bestand:
+  * 3 Gewässern mit Saar, Mosel und Elbe
+  * 15 Pegel
+  * 108 wst/zus-Dateien
+   * 711 Spalten aus diesen
+   * rund 500.000 Einzelwerte

+   
+  * Eingabe von Strecken (Wasserstand/Wasserspiegellage)
+   * Freie Texteingabe
+   * Unterstützung der Eingabe durch Auswahltabellen an Streckenfavoriten. Per Klick wird jeweils der Wert in das Textfeld eingetragen.
+   * Übernehmen von Beginn einer Strecke und Ende einer Strecke aus den Ortsfavoriten mit explizitem Setzen von Beginn (grüne Fahne) und Ende (Rote Fahne) (Erweiterung zu Desktop-FLYS)
+   * Bemerkungen:
+    * Es gibt Streckendaten, die außerhalb der Berechnungsstrecke des Modells liegen. Können die Ortsfavoritenbestände hierauf reduziert werden, da hier keine Ermittlung von Wasserständen erfolgen kann bzw. Favoriten außerhalb der Bezugspegelstrecken erlauben keine Ermittlung eines Bezugspegels.
+
+ * Automatische Ermittlung des Bezugspegels (Keine Entsprechung in Leistungsbeschreibung. Neue Anforderung als Ergebnis des Bedienkonzeptes.)

+--- Generated by GWT WebAppCreator ---
+
+Congratulations, you've successfully generated a starter project!  What next?
+
+-- Option A: Import your project into Eclipse (recommended) --
+
+If you use Eclipse, you can simply import the generated project into Eclipse.
+We've tested against Eclipse 3.4 and 3.5.  Later versions will likely also
+work, earlier versions may not.
+
+If the directory containing this file does not have a .classpath or .project
+file, generate them by running 'ant eclipse.generate'
+
+In Eclipse, go to the File menu and choose:
+
+  File -> Import... -> Existing Projects into Workspace
+
+  Browse to the directory containing this file,
+  select "FLYS".
+  
+  Be sure to uncheck "Copy projects into workspace" if it is checked.
+  
+  Click Finish.
+  
+You can now browse the project in Eclipse.
+
+To launch your web app in GWT development mode, go to the Run menu and choose:
+
+  Run -> Open Debug Dialog...
+
+  Under Java Application, you should find a launch configuration
+  named "FLYS".  Select and click "Debug".
+
+  You can now use the built-in debugger to debug your web app in development mode.
+
+If you supplied the junit path when invoking webAppCreator, you should see
+launch configurations for running your tests in development and production
+mode.
+
+-- Option B: Build from the command line with Ant --
+
+If you prefer to work from the command line, you can use Ant to build your
+project. (http://ant.apache.org/)  Ant uses the generated 'build.xml' file
+which describes exactly how to build your project.  This file has been tested
+to work against Ant 1.7.1.  The following assumes 'ant' is on your command
+line path.
+
+To run development mode, just type 'ant devmode'.
+
+To compile your project for deployment, just type 'ant'.
+
+To compile and also bundle into a .war file, type 'ant war'.
+
+If you supplied the junit path when invoking webAppCreator, you can type 'ant
+test' to run tests in development and production mode.
+ 
+For a full listing of other targets, type 'ant -p'.
+
+-- Option C: Using another IDE --
+
+GWT projects can be run in other IDEs as well, but will require some manual
+setup.  If you go this route, be sure to:
+
+* Have your IDE build .class files into 'war/WEB-INF/classes'.
+* Add gwt-user.jar and gwt-dev.jar to your project build path.
+* When creating a launch configuration, add a classpath entry for your 'src'
+  folder (this is somewhat unusual but GWT needs access to your source files).
+
+If you get stuck, try to mimic what the Ant 'build.xml' would do.
+
+-- Option D: Using Maven --
+
+If you have generated your project with the option '-maven', you have a 'pom.xml'
+file ready to use. Assuming you have 'maven2' installed in your system, 'mvn' is 
+in your path, and you have access to maven repositories, you should be able to run:
+
+mvn clean         # delete temporary stuff
+mvn test          # run all the tests (gwt and junit)
+mvn gwt:run       # run development mode
+mvn gwt:compile   # compile to javascript
+mvn package       # generate a .war package ready to deploy
+
+For more information about other available goals, read maven and gwt-maven-plugin 
+documentation (http://maven.apache.org, http://mojo.codehaus.org/gwt-maven-plugin)
