+
+	* src/main/java/de/intevation/flys/client/client/event/OnMoveHandler.java,
+	  src/main/java/de/intevation/flys/client/client/event/OnMoveEvent.java:
+	  New. Necessary classes and interfaces for a listener mechanism that is
+	  used to inform handlers about a movement. E.g. the movement of a theme.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ThemeNavigationPanel.java:
+	  New. A panel that consist of four buttons that throw OnMoveEvents after
+	  pushing it.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartThemePanel.java:
+	  In addition, it implements the OnMoveHandler interface to listen to move
+	  events.
+
+	  NOTE: We need to implement the code that moves themes up/down.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  Set the minimum width of the theme panel to 200px.
+
+2011-05-25  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/services/CollectionAttributeService.java,
+	  src/main/java/de/intevation/flys/client/client/services/CollectionAttributeServiceAsync.java,
+	  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:
+	  Changes in the theme panel will now trigger the update process of the
+	  collection's attribute using the CollectionAttributeService.
+
+	* src/main/webapp/WEB-INF/web.xml: Registered the new service.
