Re: [Springframework-rcp-dev] Tiger and Enums

Hi Benoit,

I've also come across this problem. If the enum value that you don't 
want to show are consistent throughout your application, you could 
modify the enumcomboboxbinder to only show values for which you have 
provided a message. Then in your messages you omit the messages for the 
values you don't want to show.

Something like this:

@SuppressWarnings("unchecked")
     private List<Enum> createEnumSelectableItems(FormModel formModel, 
String formPropertyPath)
     {
         Class propertyType = getPropertyType(formModel, formPropertyPath);
         Class<Enum> enumPropertyType = propertyType;
         List<Enum> out = new ArrayList<Enum>();

         for (Enum e : enumPropertyType.getEnumConstants())
         {
             String desc = getMessage(enumPropertyType.getName() + "." + 
e.name());
             if (!StringUtils.isEmpty(desc))
             {
                 out.add(e);
             }
         }

         // return enumPropertyType.getEnumConstants();
         return out;
     }

and in your createListBinding of your ...Binder you use

binding.setSelectableItems(createEnumSelectableItems(formModel, 
formPropertyPath));

That's how I solved it. I had to rewrite TigerEnumComboboxBinder since 
message handling over here is a bit different than standard RCP.

Grtz,

Lieven
