+	flys/issue298 (Karte: Automatischer Zoom auf Berechnungsergebnisse)
+
+	* src/main/java/de/intevation/flys/wsplgen/FacetCreator.java: Added a
+	  debug statement that prints out the WSPLGEN extent.
+
+	* src/main/java/de/intevation/flys/exports/MapGenerator.java: Create new
+	  Envelope instances for initial and max extent if they are not existing.
+	  Some debug statements have now been removed.

 2011-01-06	Felix Wolfsteller	<felix.wolfsteller@intevation.de>
 
 	Add cache for 'static' wqkms (e.g. BaseData) to default cache conf.
