+	* src/main/java/de/intevation/gnv/action/ChangeOptionsAction.java: Parse
+	  user input from chart/histogram options panel and check if integer and 
+	  doubles are valid - if we find a value which is not valid for the 
+	  configured type, we set an exception message which is displayed in the 
+	  chart/histogram options panel and sets the corresponding parameter to its
+	  default value.
+
+	* src/main/webapp/WEB-INF/jsp/includes/display_histogram_options_inc.jsp,
+	  src/main/webapp/WEB-INF/jsp/includes/display_diagramm_options_inc.jsp:
+	  Display error message in options panel if there is one.
+
+	* src/main/resources/applicationMessages_en.properties,
+	  src/main/resources/applicationMessages.properties:
+	  Added strings to display error messages when the user entered a bad
+	  formatted number in chart/histogram options panel.
