+
+	Extract selected data from datacage panel
+
+	* src/main/java/de/intevation/flys/client/server/meta/Converter.java:
+	  Removed some debugging.
+
+	* src/main/java/de/intevation/flys/client/shared/model/ToLoad.java: New.
+	  Contains artifact id, db ids, factory name and facet number. Should
+	  be enough to identify the data to load.
+	* src/main/java/de/intevation/flys/client/shared/model/AttrList.java:
+	  Fixed indexing bug.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DatacageWindow.java:
+	  Added a toLoad() method which returns a list of ToLoad data to load via
+	  the corresponding factories.
+	  If you double click on a tree node all data below this filled into this list
+	  and the window is disposed.
+	  You can do multipl selects on the and press the '+' button to do
+	  a multiselect loading.
