+
+	* src/main/java/de/intevation/flys/client/client/ui/WQAdaptedInputPanel.java:
+	  Set initial mode to Q.
+
+2011-06-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* Changes: Prepared changes for the upcoming release.
+
+2011-06-26	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/**/*.java:
+	  Removed trailing whitespace.
+
+2011-06-26	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/UserCollectionsServiceImpl.java,
+	  src/main/java/de/intevation/flys/client/shared/model/CollectionRecord.java,
+	  src/main/java/de/intevation/flys/client/client/ui/chart/PanControl.java:
+	  Removed superfluous imports.

+2011-06-24  Ingo Weinzierl <ingo@intevation.de>
+
+	  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,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java:
+	  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
+	  methods to dump the objects to GWT log.

+
+2011-06-23  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  Removed the formatter that cuts out a piece of the middle of project
+	  names.
+
+2011-06-23  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/CollectionRecord.java:
+	  Store Html escaped strings as names.

+	  Display the project's name stored at the CollectionRecord which is Html
+	  escaped.

+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java:
+	  Added more i18n strings for the project list and error messages.
+
+	* 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>
+
+	* pom.xml: Added dependency to Apache Commons Lang 2.6 http://commons.apache.org/lang/
+	  Used for proper HTML string escaping.
+
+	* src/main/java/de/intevation/flys/client/server/ReportServiceImpl.java: Generate
+	  error reports as HTML lists.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java: Set report
+	  in corresponding panel.
+
+2011-06-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

+
+2011-06-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants.java:
+	  Added a new error string.
+
+	* src/main/java/de/intevation/flys/client/client/ui/WQAdaptedInputPanel.java:
+	  Display a warning if there are no information of W and Q ranges that
+	  might be used to validate user input.
+
+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:
+	  If an open project is removed (via context menu) the related
+	  CollectionView is removed from screen.
+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: Added a method
+	  that returns the current FLYSWorkspace.
+

+	  Added a method that destroys a CollectionView if it is open.
+
+2011-06-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/DoCollectionAction.java:
+	  New. This base RPC service implementation handles collecion specific
+	  actions. It has a doAction() method that takes a Collection, the action
+	  document and a server url.
+
+	* src/main/java/de/intevation/flys/client/server/SetCollectionNameServiceImpl.java,
+	  src/main/java/de/intevation/flys/client/server/DeleteCollectionServiceImpl.java,
+	  src/main/java/de/intevation/flys/client/server/SetCollectionTTLServiceImpl.java:
+	  Trigger the collection actions on the server using the
+	  DoCollectionAction class which handles the Http stuff.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  Bugfix: If no user collections returned, we will clear the project list.
+
+2011-06-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/services/SetCollectionNameServiceAsync.java,

+	  src/main/java/de/intevation/flys/client/server/SetCollectionNameServiceImpl.java:
+	  New. This service is used to set the name of a collection. Note, that
+	  this is currently just a stub. The ServiceImpl currently throws a "NOT
+	  IMPLEMENTED" exception.
+
+	* src/main/java/de/intevation/flys/client/client/services/SetCollectionTTLServiceAsync.java,
+	  src/main/java/de/intevation/flys/client/client/services/SetCollectionTTLService.java,
+	  src/main/java/de/intevation/flys/client/server/SetCollectionTTLServiceImpl.java:
+	  New. This service is used to set the time-to-live of a collection. Note,
+	  that this is currently just a stub. The ServiceImpl currently throws a
+	  "NOT IMPLEMENTED" exception.

+	* src/main/java/de/intevation/flys/client/client/services/DeleteCollectionServiceAsync.java,
+	  src/main/java/de/intevation/flys/client/client/services/DeleteCollectionService.java,
+	  src/main/java/de/intevation/flys/client/server/DeleteCollectionServiceImpl.java:

+
+	* src/main/webapp/WEB-INF/web.xml: Registered the new services.
+
+2011-06-22  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:
+	  There are setter methods for 'name' and 'ttl' now. The project list
+	  requires this to set those attribute to a new value.
+
+	* 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 strings for the project list's context menu item "rename project".
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  Added a context menu item to rename the selected project and listeners
+	  to trigger setting 'name' and 'ttl' to a new value.
+
+	  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:

+	  Adapted the layout to fit the (long) german wq mode string.
+
+2011-06-22  Ingo Weinzierl <ingo@intevation.de>

+	  flys/issue104 (W-INFO: Wasserspiegellagenberechnung / Strecke)
+
+	* src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java:

+	  front and their size is restored.
+

+	  Build ReportModes for 'report' outs.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:

+	  src/main/java/de/intevation/flys/client/shared/model/Collection.java:
+	  Adapted the constructor calls. They require a time-to-live attribute
+	  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
+	  favorite state of the project. A gold star means, the project is marked
+	  as favorite, a silver one means that the project is no favorite project.
+
+	* src/main/java/de/intevation/flys/client/shared/model/CollectionRecord.java:
+	  The 'ttl' attribute returns the filename of the icon that should be
+	  displayed in the project list.
+
+	* src/main/webapp/images/star_silver.png,
+	  src/main/webapp/images/star_gold.png: New. These icons - based on icons
+	  copied from famfamfam - are used to mark a project as favorite or no
+	  favorite.
+
+2011-06-21	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/config.xml:
+	  Set project list update interval to 5 minutes. That is enough
+	  for long living projects.
+
+2011-06-21  Ingo Weinzierl <ingo@intevation.de>
+
+	  flys/issue22 (Abgelaufene Projekte/Collections werden noch in der Projektliste angezeigt.)
+
+	* src/main/java/de/intevation/flys/client/client/Config.java,
+	  src/main/java/de/intevation/flys/client/client/config.xml:
+	  Added a config option to specify the update interval of the project
+	  list. This value is retrievable using the method
+	  Config.getProjectListUpdateInterval().
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  Added a timer to update the user's collections frequently. The interval
+	  is determined by the constant UPDATE_INTERVAL which is currently 30
+	  seconds or a config.xml option that needs to be configured at
+	  "/config/projectlist/update-interval/text()".
+
+2011-06-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,

+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java,
+	  src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java:
+	  'boolean ? true : false' <=> 'boolean'
+	
+2011-06-20	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/DescribeCollectionServiceImpl.java:
+	  Removed more expensive XPath.

+
+	* src/main/java/de/intevation/flys/client/client/ui/wq/QDTable.java:
+	  New. This table is used to show Q and D values for the WQInputPanel. The
+	  first two rows are selectable icons.
+
+	* src/main/java/de/intevation/flys/client/client/ui/wq/WTable.java: New.
+	  This table is used to show W values for the WQInputPanel. The rows in
+	  this table are not selectable.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DoubleRangePanel.java:
+	  Added methods to set the lower and upper value directly.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DoubleArrayPanel.java:
+	  Added a method to add a further double value to the current list.
+
+	* src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java:
+	  Removed the old WQD tables and replaced them with a QDTable and a
+	  WTable. The WQD values are sorted into the two tables when they are
+	  initialized. The values in the WTable are not selectable. The QDTable
+	  has two selectable columns. Based on the current mode (single values or
+	  range mode), the selected values are filled into the array panel or into
+	  the range panel.

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

+2011-06-06  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:

+
+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

+	  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

+
+	* 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:

+
+	* 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>

+
+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

+
+2011-06-01  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:

+	  Collection.
+
+	  NOTE: Maybe we need to introduce a mechanism to mark the artifact that

+
+2011-03-28  Ingo Weinzierl <ingo@intevation.de>
+

+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  The artifact is put into the collection (or new collection) if we reach

+
+2011-03-25  Ingo Weinzierl <ingo@intevation.de>

+
+2011-03-25  Raimund Renkert <rrenkert@intevation.de>
+

+	* src/main/java/de/intevation/flys/client/shared/model/Facet.java,
+	  src/main/java/de/intevation/flys/client/shared/model/DefaultFacet.java:

+
+	* 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

+
+2011-03-23  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/ArtifactDescription.java:

+
+	* src/main/java/de/intevation/flys/client/shared/model/DefaultArtifactDescription.java:
+	  Implemented the method to retrieve the available output modes and

+
+2011-03-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/webapp/images/next.xcf: Moved to images/next.xcf to avoid that

+
+2011-03-21  Ingo Weinzierl <ingo@intevation.de>
+

+	  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:
+	  The methods that validates a FormItem will skip StaticTextItem

+
+	* 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).

+	  This view will now display radio buttons to choose between the module
+	  'WINFO', 'MINFO', 'Map' and 'Fix-Analyse'. A button is shown to create an
+	  artifact of the selected module.
+
+	  NOTE: The next step here is to use the returning artifact with its
+	  description and display widgets based on these information.

+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: The
+	  FLYSWorkspace is created here. FLYS stores a reference to it and puts the
+	  workspace into the FLYSView. Furthermore, there is a new method that
+	  creates new Collections.
+
+	  NOTE: Currently, there is no communication with the artifact server,
+	  because Collections aren't implemented yet!
+
+2011-02-11  Ingo Weinzierl <ingo@intevation.de>

+
+2011-02-10  Ingo Weinzierl <ingo@intevation.de>
+

+	  mockup. This code needs to be removed after a service to fetch the user
+	  collections has been implemented.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionGrid.java:

+
+	  NOTE: The buttons have no effect yet.
+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: The FLYS class
+	  has a reference to the ProjectList. If a logged in user was found, the
+	  ProjectList is initialized and added to the FLYSView.
+
+	* src/main/java/de/intevation/flys/client/client/ui/FLYSView.java: There is
+	  a new method to set the ProjectList. Furthermore, all UI components are
+	  put into a HLayout now. On this way, we are able to open/close the
+	  ProjectList.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages.java,
+	  src/main/java/de/intevation/flys/client/client/FLYSMessages_en.properties,

+
+2011-02-10  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: The
+	  interface and its default implementation of a Collection.
+	  NOTE: I think both classes will change pretty much, but they have been
+	  necessary for the ProjectList mockup.
+
+2011-02-10  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/FLYS.gwt.xml: The artifact-common
+	  package is available in the GWT code now.
+
+	* pom.xml: Made the artifact-common package available.
+
+	* src/main/java/de/intevation/flys/client/server/UserServiceImpl.java,
+	  src/main/java/de/intevation/flys/client/client/services/UserService.java,
+	  src/main/java/de/intevation/flys/client/client/services/UserServiceAsync.java:
+	  A service definition that retrieves user information. Currently, this
+	  service defines a single method that returns the user that is currently
+	  logged in.
+
+	* src/main/webapp/WEB-INF/web.xml: Added a servlet definition that provides
+	  the UserService.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSMessages_en.properties,

+2011-06-27  RELEASE 2.4
+
+    NEW:
+
+        * Introduced:
+          - a theme panel on the left of the chart. It allows to change
+            the state and order of the themes in the chart.
+          - a panel that displays the current mouse position in chart
+            coordinates.
+          - a Zoombox-Control that allows zooming in charts via zoombox.
+          - a control to zoom out for 10%.
+          - a control to zoom to the max extent of the chart.
+          - a control to pan charts.
+          - a panel that displays reports generated by calculations.
+          - a client side validation of user input.
+
+        * Improved the project list. The user can now rename projects and set
+          favorite projects that will never be deleted.
+
+        * Improved the chart output service to support zoom values.
+
+        * Added new services to:
+          - set the Collection's attribute to a new value
+          - set the name of a project
+          - set the time-to-live of a project
+          - delete a project
+          - retrieve meta information of the current chart
+            This service returns a ChartInfo object that stores information about
+            the axes ranges, data ranges and a transformation matrix to transform
+            image coordinates into chart coordinates
+          - fetch calculation reports
+
+        * flys/issue40 Input fields will show former selected values.
+
+    FIXES:
+
+        * flys/issue21 Projects cannot be opened twice but if a projects is
+          already open, it is brought to foreground.
+
+        * flys/issue22 Introduced a polling for user projects. Dead projects are
+          automatically removed.
+
+        * flys/issue43 I18N adjustments.
+
+        * flys/issue85 Location/Distance panel now distinguishes between these
+          two modes. Two (or more) locations will no longer end up in a distance.
+
+        * flys/issue88 I18N adjustments in the location/distance panel.
+
+        * flys/issue91 The WQ panel's initial mode is Q.
+
+        * flys/issue103 Append units in WQ panel.
+
+        * flys/issue104 The selected WQ mode is displayed in the static panel
+          now.
+
+        * flys/issue117 DoubleArrayPanel and DoubleRangePanel will no longer
+          return duplicate values.
+
+        * flys/issue118 The WQ panel has three modes now: W at gauge, Q at
+          gauge and Q free.
+
+        * flys/issue122 The values in the table displaying W values are no
+          longer selectable.
+
+        * flys/issue132 The initial location/distance mode is now distance.
+
+        * flys/issue139 Fixed NPE while initialising user values in the adapted
+          WQ panel.
+
+        * flys/issue140 Splitted the table - displaying W, Q and D values - up
+          in two tables for W (no longer selectable) and for QD.
+
+        * flys/issue156 The report panel is not displayed as tab besides the
+          chart tabs.
+
+        * flys/issue165 Limit the length of new project names to 50 characters.
+
+        * flys/issue170 Fixed broken initial chart info.

+        * flys/issue23 (Doppel-Click auf Eintrag in der Projektliste sollte ein Projekt öffnen)
+
+        * flys/issue35 The project window is maximizable with a 'maximize' button.
+
+        * flys/issue38 (WINFO: Vorbelegung der Berechnungsart auf "Wasserstand/Wasserspiegellagen")
+
+        * flys/issue39 (WINFO: Auswahl einer Strecke in bei Eingabeunterstützung liefert nicht die richtigen Werte)
+
+        * flys/issue43 (i18n: Einige Verbesserungen)
+
+        * flys/issue44 (WINFO: Unterstützungstabellen werden in fester Fensterbreite angezeigt)
+
+        * flys/issue45 (WINFO: Ladedialog bei Laden der Daten in Unterstützungstabellen anzeigen)
+
+        * flys/issue48 (Diagramm: Bereiche für Themensteuerung und Werkzeugleiste vorgeben.)
+

+
+
+
+2011-05-13  RELEASE 2.3
+
+    NEW:
+
+        * Initial GWT/Ajax based Web-Client for the REST based artifact system:
+          - Renderer for states specific for WINFO artifact
+          - Panels for W/Q selection
+          - Panels for Range selection
+          - Chart panels for chart output creation
+          - Export panels that provides download links for exporting computation
+            data
+          - Project list displays former projects that might be opened by
+            double click
+          - Datacage (dt. 'Datenkorb') UI that displays loadable data for charts
+
+        * RPC-services enable data exchange between client and server
+
+        * Connection settings are configured in config.xml
+
+        * I18N is splitted into two parts and support English and German:
+          - GUI elements are translated using the GWT i18n mechanism
+          - Information/data served by the artifact system is translated by the
+            artifact server
+
+
+    LIMITATIONS:
+
+        * Language switch drops the current session
+
+        * Charts served by the artifact system are rendered as PNG only
+
+        * Theme control for charts is not implemented yet.
+
+        * Data served by the datacage can't be added to projects/charts
+
+
+    !!!
+
+    The version number of this release depends on an existing desktop variant of
+    this software that is in version 2.1.

+ 
+
+=== WINFO ===
+
+  * Wahl von Abflüssen, Wasserständen und Dauerzahlen (Pflichtenheft: Bestehende Funktionen aus Desktop-FLYS; keine Entsprechung in Leistungsbeschreibung)
+   * WINFO: Q/W/D-Info liefert selten eine Antwort (https://roundup-intern.intevation.de/flys/issue72)
+
+ * Berechnungsausgabe (Pflichtenheft: Teile in Kap. 3.4.1.1; bestehende Funktionen aus Desktop-FLYS + Verbesserungen)
+  * Ergebnisse werden jeweils im WST-Format ausgegeben (https://roundup-intern.intevation.de/flys/issue56)
+   * Auf Berechnungsergebnisse zu korrigierten Wasserstands-Abflussbeziehungen können über CSV-Dateien zugegriffen werden
+
+ * Zu berücksichtigende Punkte bei der Durchführung der Berechnungsarten
+  * Allgemein:
+   * Besondere Beachtung der Berücksichtigung des Rücksprungverhaltens
+  * Wasserspiegellage/Wasserstand
+   * Berechnungsart 1 "Wasserstand/Wasserspiegellage" fehlerhaft (https://roundup-intern.intevation.de/flys/issue69)
+  * Abflusskurve/-tafel
+   * Weitere Infos zu Fällen für Rücksprünge werden benötigt.
+  * Dauerlinie
+   * WINFO: CSV-Export für Dauerlinien fehlt (https://roundup-intern.intevation.de/flys/issue79)
+    * Wird zur fachlichen Abnahme noch nachgereicht.
+  * W bei ungleichmäßigem Abflusslängsschnitt
+   * WINFO: Reihenfolge der Kilometer Eingabe liefert unterschiedliche Ergebnisse (https://roundup-intern.intevation.de/flys/issue71)
+   * WINFO: Gewichtungsfaktor für Abflusstabellen in der Berechnung "W für angepaßten Abfluss-Längsschnitt" (https://roundup-intern.intevation.de/flys/issue55); hier ist das Vorgehen zur Intervallbildung noch zu klären.
+
+
+
+=== Diagramme ===
+  * Allgemein:
+   * Beschriftung der Legendeneinträge zu Kurven zu Eingangswerten in die Berechnung (https://roundup-intern.intevation.de/flys/issue77)
+    
+ 
+=== Offene Punkte ===
+ * Version 2.3.1 behebt Fehler und ergänzt eine Funktion. Punkte mit noch nicht bereitgestellten Funktionen finden sich unter [[Flys-3.0/Version2.3Todo]].
+ 
+
+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
+  * rund 2.500 Stationierungen aus km-Dateien
+ 
+
+=== WINFO ===
+
+ * Wahl des Gewässers (Pflichtenheft, Teile aus 3.4.1, 3.4.1.1)
+  * Automatische Vorbelegung des ersten Eintrags
+
+ * Wahl der Berechnungsart (Pflichtenheft 3.4.1.1 - bestehende Funktionen)
+  * Automatische Vorbelegung des ersten Eintrags
+  * Umsetzung der folgenden Berechnungsarten
+   * Wasserstand/Wasserspiegellage
+   * Abflusskurve/Abflusstafel
+   * Dauerlinie
+   * W bei ungleichmäßigem Abflusslängsschnitt
+
+ * Wahl von Strecke oder Ort (Pflichtenheft: Bestehende Funktionen aus Desktop-FLYS; keine Entsprechung in Leistungsbeschreibung)
+
+   * Automatisches Umschalten der Reiter bei Wahl von Orten oder Strecken
+
+  * Eingabe eines Ortes (Dauerlinie, Abflusstafel/-kurve)
+   * Freie Texteingabe
+   * Unterstützung der Eingabe durch Liste an Ortsfavoriten. Per Klick wird jeweils der Wert in das Textfeld eingetragen.
+
+  * Eingabe mehrere Orte (Wasserstand/Wasserspiegellage)
+   * Freie Texteingabe
+   * Unterstützung der Eingabe durch Auswahltabellen an Ortsfavoriten. Per Klick wird jeweils der Wert in das Textfeld eingetragen.
+   * Übernehmen von Beginn einer Strecke und Ende einer Strecke (abweichend von Desktop-FLYS, um die Bedienführung gradliniger zu gestalten)
+   
+  * 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.)
+  * Gewässer und Streckenwahl ermitteln den Bezugspegel automatisch
+  * Anzeige der Abflusskurven aller Pegel auf der vorgegebenen Strecke
+
+  * Wahl von Abflüssen, Wasserständen und Dauerzahlen (Pflichtenheft: Bestehende Funktionen aus Desktop-FLYS; keine Entsprechung in Leistungsbeschreibung)
+   * Berechnungsart: Wasserspiegellagen/Wasserstand
+    * Eingabefelder wie in Desktop-FLYS für W oder Q; Einzelwerte oder Wertebereich
+    * Eingaben werden über eine tabellarische Auswahl unterstützt
+     * Bei der Eingabe von W: Wasserstände sind auswählbar
+     * Bei der Eingabe von Q: Hauptwerte und Dauerzahlen sind auswählbar
+   * Berechnungsart: W bei ungleichmäßigem Abflusslängsschnitt
+    * Eingabefelder für W und Q analog zu bisherigen genutzten Mechanismen
+
+ * Berechnungsausgabe (Pflichtenheft: Teile in Kap. 3.4.1.1; bestehende Funktionen aus Desktop-FLYS + Verbesserungen)
+  * Ausgabe jeweils in einer strukturierten Tabelle.
+  * Die Werte können in Abhängigkeit von der Spalte auf- und absteigend sortiert werden.
+  * Ergebnisse werden jeweils im CSV-Format ausgegeben
+  * Es werden weitere Ausgaben in zusätzlichen Reitern angezeigt, die auch abgefragt werden können.
+
+=== Diagramme ===
+  * Allgemein:
+   * Integrierte Ausgabe der Diagramme in WINFO (Pflichtenheft Kap. 3.1)
+   * Zugriff auf die Projektdefinition/Parameterisierung (WINFO-Reiter)
+   * Freie Größenskalierung der Diagramme in Abhängigkeit vom Projektfenster
+   * Internationalisierung der Diagramme in deutsch und englisch (Beschriftung, Dezimaltrennzeichen und Tausendertrennzeichen)
+   * Beschriftung der Diagrammtitel gemäß Anhang (Leistungsbeschreibung, Anhang 1)
+    
+  * Anpassungen in Abhängigkeit von Berechnungsart/Diagrammtyp (Bestehendes Verhalten aus Desktop-FLYS):
+   * Abflusskurve am Pegel

+--- 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)
