+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Added methods to add and remove Layer instance to/from Map and grant
+	  public access to createWMSLayer() method.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ThemePanel.java: Moved
+	  code to add new FacetRecords to the grid to an own method
+	  addFacetRecord().
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapThemePanel.java:
+	  Override addFacetRecord() to be able to detect new FacetRecords. In this
+	  case, we gonna create new WMS layers based on the FacetRecord and add a
+	  new Layer object to the Map.
+	  Override createRemoveItem() which removes a layer from Map and from
+	  ThemePanel.
