+2012-02-13  Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	Partial fix for flys/issue499 (Wasserspiegellagen: Berechnung für W frei und Pegel kaputt)
+	There are still validation issue in the client.
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+	  Fixed state evaluation for "W auf freier Strecke"/"W am Pegel".
+	  There is still an issue in the client with the input validation
+	  which prevents entering the right W values for 
+	  "W auf freier Strecke". :-/
+
+2012-02-13  Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java:
+	  Make it compilable again.

 	Partial Fix flys/issue500: text-backgrounds for manual points.
