Re: Checkbox and enum value
i'm sorry i didn't see this post before-- i came up with a solution a couple of weeks ago. i called it EnumCheckGroup (that is, i went for CheckGroup rather than CheckBox). usage: for a given enum: public static enum Niveau { etage, mezzanine, sous_sol; } form.add(new EnumCheckGroupPlan.Niveau(niveaux, Plan.Niveau.values())); span wicket:id=niveaux span wicket:id=items input type=checkbox wicket:id=check / span wicket:id=label/spanbr / /span /span impl: public class EnumCheckGroupT extends EnumT extends CheckGroupT { public EnumCheckGroup(String id, T[] values) { super(id); ListViewT listview = new ListViewT(items, Arrays.asList(values)) { protected void populateItem(ListItemT item) { item.add(new CheckT(check, item.getModel())); item.add(new Label(label, new ResourceModel(item.getModelObject().name(; }; }.setReuseItems(true); add(listview); } } obviously you must have the keys in your properties file, such as: etage=Étage mezzanine=Mezzanine sous_sol=Sous-sol francisco On Fri, Sep 26, 2008 at 4:29 PM, Cédric Thiébault [EMAIL PROTECTED] wrote: Thanks Igor, it was exactly what i needed :-) To complete this post, here is the solution I found : http://surunairdejava.blogspot.com/2008/09/wicket-checkbox-abstractcheckboxmodel.html Sorry it's in french but the code is easy to understand...

Re: Checkbox and enum value
Why not just pass the enum class into the constructor? But, also have one that allows you to provide a subset of enum values (as you already have).

Also, you could have a varargs feature so that users could specify exactly what they want without having to instantiate an array.
