+
+	* Changes, NEWS, ChangeLog: Summarized changes.
+
+2010-04-28  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	* src/main/java/de/intevation/gnv/servlet/GNVActionServlet.java: Removed
+	  trailing whitespace.
+
+2010-04-28  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	* src/main/java/de/intevation/gnv/action/DescribeUIAction.java: Removed
+	  duplicated and unused imports.
+
+2010-04-27  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue225
+
+	* src/main/webapp/WEB-INF/config/struts-config.xml: Added global forwards
+	  for imprint and info.
+
+	* src/main/webapp/WEB-INF/jsp/header.jsp,
+	  src/main/webapp/WEB-INF/jsp/footer.jsp: Adapted links for imprint and info
+	  pages.
+
+	* src/main/webapp/WEB-INF/jsp/imprint.jsp,
+	  src/main/webapp/WEB-INF/jsp/info.jsp: New pages for imprint and an info
+	  page.
+
+	* src/main/resources/applicationMessages_en.properties: Renamed 'about' ->
+	  'imprint'.
+
+2010-04-27  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue225
+
+	* src/main/webapp/WEB-INF/config/templates/describe-ui.xsl: Render a
+	  parameter matrix if there is just a single parameter as well. This allows
+	  us to render a legend for multi select boxes at another place - this fixes
+	  the missing legend for parameter select boxes.
+
+2010-04-26  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	* src/main/webapp/images/img.gif,
+	  src/main/webapp/images/stock_data-save.png,
+	  src/main/webapp/images/bg_fieldset.gif,
+	  src/main/webapp/images/list-item.gif,
+	  src/main/webapp/images/bg_fieldset_ie6.gif,
+	  src/main/webapp/scripts/calendar-setup.js,
+	  src/main/webapp/scripts/calendar-en.js,
+	  src/main/webapp/scripts/calendar.js,
+	  src/main/webapp/scripts/calendar-de.js,
+	  src/main/webapp/scripts/calendar-setup_stripped.js,
+	  src/main/webapp/scripts/jquery-1.4.2.min.js,
+	  src/main/webapp/scripts/calendar_stripped.js: Removed JavaScript files and
+	  images that are not used anymore.
+
+2010-04-26  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	* src/main/resources/applicationMessages.properties,
+	  src/main/resources/applicationMessages_en.properties: Added an error
+	  message if that should be displayed if an artifact is out of date.
+
+2010-04-26  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue236 & Issue242
+
+	* src/main/java/de/intevation/gnv/action/FetchArtifactFactoriesAction.java,
+	  src/main/java/de/intevation/gnv/action/DescribeUIAction.java: Display
+	  error messages if the artifact server is down - this have been broken.
+
+2010-04-26  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue258
+
+	* src/main/java/de/intevation/gnv/action/LoadAction.java: An error message
+	  is displayed if the user tried to load an existing project and the
+	  artifact server is down.
+
+2010-04-26  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue259
+
+	* src/main/webapp/WEB-INF/jsp/includes/display_diagramm_options_inc.jsp:
+	  Added target 'chart' as url request parameter when performing the html 
+	  form to change the chart output. The reason for doing this is, that the
+	  InternetExplorer seems no to add the value of <input type="image"...>
+	  elements to the request object which is sent to the server.
+
+2010-04-26  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue225
+
+	* src/main/webapp/styles/gnv.css: Reduced the size of links in header and
+	  footer.
+
+2010-04-26  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue225
+
+	* src/main/webapp/styles/gnv.css: Adjusted the style of fieldsets - there is
+	  a gap between the fieldset border and input elements in IE now as well.
+	  The size of select boxes and textareas is fixed now.
+
+2010-04-25  Ingo Weinzierl <ingo_weinzierl@web.de>
+
+	  Issue225
+
+	* src/main/webapp/styles/gnv.css: A new style class. Most of this is copied
+	  from default.css but a lot of content which is not used anymore has been
+	  removed.
+
+	* src/main/webapp/WEB-INF/jsp/index.jsp: Restructuring. The parameter panel
+	  and the content div container are placed in a table row now. Very wide 
+	  html elements in the content div container don't break the layout anymore.
+
+	* src/main/webapp/WEB-INF/jsp/wmslayout.jsp: Moved html elements to render
+	  OpenLayers into index.jsp. Removed JavaScript code to adjust layout.
+
+	* src/main/webapp/WEB-INF/jsp/includes/display_diagramm_options_inc.jsp:
+	  Added style class to the table that contains the chart options.
+
+	* src/main/webapp/WEB-INF/jsp/mainlayout.jsp: Removed JavaScript code to
+	  adjust layout.
+
+	* src/main/webapp/scripts/jquery-1.4.2.min.js: Removed. Not used anymore.
+
+2010-04-23  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue225
+
+	* src/main/webapp/styles/default.css: Adapted some font size in the
+	  parameter panel.
+
+2010-04-23  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue225
+
+	* src/main/webapp/WEB-INF/jsp/index.jsp: Replaced the standard html input
+	  button with an image as the choose button.
+
+	* src/main/resources/applicationMessages.properties,
+	  src/main/resources/applicationMessages_en.properties: Added specific 
+	  strings that represent pathes to german and english load button images.
+
+	* src/main/webapp/styles/default.css: New styles to adjust the upload box
+	  and the load button.
+
+
+	* src/main/webapp/images/load.png,
+	  src/main/webapp/images/laden.png: Images for project load button.
+
+2010-04-23  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue237
+
+	* src/main/webapp/WEB-INF/jsp/wmslayout.jsp: Added http request parameter to
+	  the mapserver path to simplify the GetCapabilities call for the user.
+
+2010-04-23  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue254
+
+	* src/main/java/de/intevation/gnv/action/SwitchLanguageAction.java: New
+	  controller to toggle between german and english language.
+
+	* src/main/java/de/intevation/gnv/action/NextArtifactStepAction.java,
+	  src/main/java/de/intevation/gnv/action/DescribeUIAction.java: Use the
+	  locale stored in the artifact to create the user interface. At the
+	  beginning, this will be the locale of the request object. If the user
+	  chooses another language by calling the SwitchLanguageAction controller,
+	  this locale becomes the prefered locale, and the browser settings are no
+	  more relevant.
+
+	* src/main/java/de/intevation/gnv/action/sessionmodel/SessionModel.java,
+	  src/main/java/de/intevation/gnv/action/sessionmodel/DefaultSessionModel.java:
+	  Now, the SessionModel has two methods to set and retrieve the current
+	  locale which is used to create a language specific user interface.
+
+	* src/main/java/de/intevation/gnv/action/sessionmodel/SessionModelFactory.java:
+	  Initial creation of the SessionModel gets the locale of the request
+	  object. If this locale is changed by the user via SwitchLanguageAction
+	  controller, changes in the browser settings won't have an effect anymore.
+
+	* src/main/webapp/WEB-INF/config/struts-config.xml: Add the controller to
+	  switch between languages.
+
+	* src/main/webapp/WEB-INF/jsp/header.jsp: The header contains a link to
+	  toggle between german and english language - a click on it will trigger
+	  the SwitchLanguageAction.
+
+2010-04-22  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue221
+
+	* src/main/java/de/intevation/gnv/action/ArtifactDatabaseActionBase.java:
+	  Added methods to quote html characters in strings.
+
+	* src/main/java/de/intevation/gnv/action/WMSAction.java: Call methods to
+	  quote html characters in strings inserted by the user. Used to be safe 
+	  from html injections.
+
+2010-04-19  Hans Plum <hans@intevation.de>
+
+	Issue 241: Set Path to Tomcat Standard Logging
+
+	* src/main/webapp/WEB-INF/classes/log4j.properties:
+	Adapted logging path for webclient gnv to the central tomcat mechamism
+	in order to resolve the dependency to the artefact-server directory
+	layout.
+
+2010-04-19  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue227
+
+	* src/main/java/de/intevation/gnv/artifactdatabase/client/ArtifactDatabaseClient.java,
+	  src/main/java/de/intevation/gnv/artifactdatabase/client/DefaultArtifactDatabaseClient.java:
+	  Added a new method to retrieve the current locale.
+
+	* src/main/java/de/intevation/gnv/action/DescribeUIAction.java: Feed the xsl
+	  transformer with a tooltip text for the back-button.

+	* src/main/resources/applicationMessages.properties,
+	  src/main/resources/applicationMessages_en.properties: Added a tooltip text
+	  for the back-button.
+
+	* src/main/webapp/WEB-INF/config/templates/describe-ui-static.xsl: Use the
+	  tooltip text that is fed in DescribeUIAction.
+
+	* src/main/java/de/intevation/gnv/action/ChangeOptionsAction.java: Removed a
+	  PropertiesReader which isn't used there.

+

+
+2010-04-09  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue210
+
+	* src/main/webapp/WEB-INF/config/templates/describe-ui.xsl: Changed the
+	  parameter-measurement matrix rendering. Its content is no more selectable
+	  - it is just to inform the user about the existence of a measurement for a
+	  given parameter. Instead, there is a new row with a checkbox for each 
+	  measurement in the header of the matrix. So, the user is able to select a
+	  measurement without a relation to a specific parameter - all parameters
+	  which are available for this measurement are effected by this choice in
+	  future outputs.
+
+	* src/main/webapp/styles/default.css: New classes for styling the
+	  parameter-measurement matrix.
+
+	* src/main/webapp/images/delete.png,
+	  src/main/webapp/images/tick.png: New icons to inform the user about the 
+	  existence of a measurement for a given parameter.
+
+2010-04-09  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	  Issue216
+
+	* src/main/webapp/WEB-INF/jsp/includes/display_diagramm_options_inc.jsp:
+	  Added a missing character to the url of the image export.

+	  describe-request to the artifact server.
+
+	* src/main/webapp/WEB-INF/config/struts-config.xml: Added a new controller
+	  to build the current user interface. This could be used if the artifact

+	  the ui with the current artifact description.
+
+	* src/main/webapp/styles/default.css: Moved exception message and reload

+	RELEASE 0.3
+
+	* Changes, NEWS, ChangeLog: Summerized activities
+
+2010-01-27  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	* src/main/webapp/WEB-INF/config/templates/describe-ui.xsl: Added a
+	  workarround to avoid input failures caused by multi select boxes with only
+	  one entry. They look like text input fields and don't force the user to 
+	  select a row. In this case, the single entry is selected automatically.
+
+2010-01-25  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	* src/main/webapp/styles/default.css: Added a class for dynamic tables 
+	  - enabled input fields - to adjust font size of input fields.

+	  local-name() method, inserted a table for 'group' items (like input fields
+	  of dates) and resized the height of multi select boxes - max 5 items or
+	  less.
+
+	* src/main/webapp/WEB-INF/jsp/index.jsp: Removed a typo which made the html
+	  output invalid.
+
+2010-01-22  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	* src/main/webapp/WEB-INF/jsp/includes/display_export_inc.jsp: Add width,
+	  height and the boolean value to adjust the visibility of points in charts 
+	  to the pdf and svg export links.
+
+2010-01-22  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	* src/main/resources/applicationMessages.properties,
+	  src/main/resources/applicationMessages_en.properties: Added legend for
+	  summary box.
+
+	* src/main/webapp/styles/default.css: Adapted some css classes regarding the
+	  position of boxes and removed background image in fieldsets.
+
+	* src/main/webapp/WEB-INF/config/templates/describe-ui-static.xsl: Removed
+	  useless div container (div container is now outside the xsl sheet).
+
+	* src/main/webapp/WEB-INF/jsp/index.jsp: Moved former parameter into a
+	  fieldset and added a label to this fieldset.
+
+2010-01-22  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	* src/main/java/de/intevation/gnv/action/ShowStatisticAction.java: This
+	  action 'calculates' the statistic and shows the result in the gui.
+	
+	* src/main/webapp/WEB-INF/config/struts-config.xml: Added controller and
+	  forwards.
+
+	* src/main/webapp/images/statistics.png: Statistic icon. FIXME: Give a Source here!
+
+	* src/main/webapp/WEB-INF/jsp/index.jsp,
+	  src/main/webapp/WEB-INF/jsp/includes/display_diagramm_statistics_inc.jsp,
+	  src/main/webapp/WEB-INF/jsp/includes/display_diagramm_inc.jsp,

+	  placement of the statistic box.
+
+	* src/main/resources/applicationMessages.properties,
+	  src/main/resources/applicationMessages_en.properties: Added label for
+	  statistic icon. 
+
+2010-01-22  Ingo Weinzierl <ingo.weinzierl@intevation.de>
+
+	* src/main/java/de/intevation/gnv/action/DescribeUIAction.java: New action.
+	  The only task of this action is to parse the describe document and create 
+	  static and dynamic user interface out of it.

+	  Removed xsl transformation. Classes which needs xsl transformation inherit
+	  from DescribeUIAction which does the transformation. Now, it is much
+	  easier to write new actions, because they do not need to parse the
+	  describe document and create static and dynamic user interfaces.
+
+	  Removed some useless imports.

+	* src/main/java/de/intevation/gnv/action/ChangeOptionsAction.java: Show
+	  chart if there are output modes existing for this state. Set internal

+	  
+	  TODO: We should check if there is an output mode named 'chart' before 
+	  rendering a chart.
+
+2010-01-20  Ingo Weinzierl <ingo.weinzierl@intevation.de>

+	  src/main/webapp/WEB-INF/jsp/index.jsp: Commented links to step back in
+	  history out and always render a fis select box (reason for this is the

+
+        * Support for changing the language between german and english via
+          button in the gui. The intial language is determined by browser
+          settings. After the user changes this settings by clicking the button
+          in the gui, the browser locale is ignored in future (#30, #254)
+
+        * Improved error handling. The user is able to reload the current
+          parameterization with the help of a link shown in the gui if an error
+          occured (#13). After clicking that link, the describe document of the
+          current artifact is requested and the gui is created again (#13, #18,
+          #236).
+
+        * Improve input validation in chart/histogram panels.
+
+        * Improve the design of the gui according to BSH style guides.
+
+    FIXES:
+
+        * Adjusted file extension of image exports (#187)
+        * Display time to live of an artifact (#197)
+        * Added missing character in the link to trigger an image export of
+          charts (#216)
+        * Restructuring of parameter-measurement matrix. Just the selection of
+          different depths is possible (#210)
+        * Added tooltip text for the step-back button (#227)
+        * Replace html characters to avoid html injections (#221)
+        * Adapted the MapServer path shown in the gui (#237)
+        * Fixed a bug in IE that avoided exporting charts as image (#259).
+        * Loading an artifact without running artifact server ends with a
+          warning and a message to try it later again (#258)
+        * Display an error message if the user tries to work with an outdated
+          artifact (#242)
+        * Repaired logging with log4j

+      artifact database.
+
+    * UI mainly inspired by the prototype from conterra.
+
+    * It implements a runtime system for working with artifacts
+      by storing a client side proxy model in the session of
+      the servlet context. The workflow is completely controlled
+      by the artifact living in the artifact database.
+
+    * The input forms are generated by XSL transformation from
+      the 'describe' output of the artifact.
+
+    * Output is rendered as PNG, downloadable PNGs, CSV and
+      statistics all produced serverside in the artifact database.
+
+    * i18n/i10n is done by Struts and broadcasted via REST to
+      the REST beased artifact database. Supported languages:
+      German and English
+
+    * The connection to the REST server is configure in web.xml
+      default: http://localhost:8181
