+
+	* src/main/java/de/intevation/gnv/action/ChangeOptionsAction.java: Store
+	  chart/histogram options inserted by the user in the SessionModel. In the
+	  case of a wrong input we are able to reuse the previous value. Options
+	  inserted by the user are stored as native objects - no longer as string.
+
+	* src/main/java/de/intevation/gnv/action/sessionmodel/DiagrammOptions.java:
+	  Store options as Object instead of String to keep the information about
+	  the type of the option (string, integer, double, etc). Furthermore there
+	  is a new method getValue(String key, Locale locale) that returns the value
+	  as string. Double values are formatted using the locale object. This
+	  method is used in the gui to display a well formatted i18n string.
+
+	* src/main/webapp/WEB-INF/jsp/includes/display_histogram_options_inc.jsp,
+	  src/main/webapp/WEB-INF/jsp/includes/display_diagramm_options_inc.jsp:
+	  Make use of the new method in DiagrammOptions to retrieve the value as
+	  formatted string.
