+
+	Improved fix for issue860 (minfo parameterization in helper pane).
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterMatrixPanel.java
+	  (createWidget, createCheckBox): Renamed.
+	  Use smartgwt stuff to profit from scrollbars (yay!).
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterMatrixPanel.java:
+	  Place ParameterMatrix in helper pane if too long.
