changeset 408:b5733f9f386b

Design improvements: Moved chart option panel and export actions beneath the parameterization panel on the left side. Do not render a useless 'draw' button after reaching the final state. gnv/trunk@594 c6561f87-3c4e-4783-a992-168aeb5c3f6f

+	  - Improved the design and the usibility concept ("Bedienkonzept").
+	    Removed the useless "draw" button after reaching the last state which 
+		has some output modes.
+	  - Render chart options - if chart creation is possible for this state - and show
+	    export actions.
+	  - Moved chart options and export actions to the left side beneath the 
+	    static and dynamic panals for parameterization.
+	  - Removed some warnings and errors regaring html conformance.
+
+	* src/main/webapp/styles/default.css: Made some necessary adjustments
+	  regarding the movement of chart option and action boxes.
+	
+	* src/main/resources/applicationMessages.properties,
+	  src/main/resources/applicationMessages_en.properties: Added label for
+	  action box.
+
+	* src/main/java/de/intevation/gnv/action/ArtifactDatabaseActionBase.java:
+	  Removed pathes of xsl sheets from code and put them to a central place.
+
+	* src/main/java/de/intevation/gnv/action/ChangeOptionsAction.java: Added
+	  urls to xsl transformer for step-back links and create a dynamic ui only
+	  if there is content for it - avoid creation of empty boxes.
+
+	* src/main/java/de/intevation/gnv/action/NextArtifactStepAction.java: Write
+	  dynamic ui only if there is content. Some code formatting done.

+	* src/main/webapp/images/back_button.png: Button to step back to a previous
+	  state.
+	  
+	* src/main/webapp/WEB-INF/config/struts-config.xml: Added forwards to fis
+	  selection and previous states.
+
+	* src/main/webapp/WEB-INF/config/templates/describe-ui-static.xsl: Enabled
