Hmm

Something seems wrong with your code or youre not providing it all. Could you create a quickstart? (simple project created with the wicket archetype, that only contains your core problem..)

Hi, i have the following codes for a dropdownchoice component.

List<String> isUserGender = Arrays.asList("M","F"); gender = new DropDownChoice("gender", new PropertyModel(User,"UserGender"), isUserGender); List<String> isUserDesignation = Arrays.asList("Operator","Custom officer", "Warehouse Supervisor", "Top Management"); designa = new DropDownChoice ("design", new PropertyModel (User,"UserDesignation"), isUserDesignation);

However, i encounterd the following error: WicketMessage: unable to set object Top Management Root cause:
wicket.WicketRuntimeException: no set method defined for value: Top
Management on object:

This error disappear after I ran the application a few times but it comes
back again after several tries. Anyone knows how to solve this? thanks
