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 EnumCheckGroup<Plan.Niveau>("niveaux",
Plan.Niveau.values()));
<span wicket:id="niveaux">
<span wicket:id="items">
<input type="checkbox" wicket:id="check" />
<span wicket:id="label"></span><br />
</span>
</span>
impl:
public class EnumCheckGroup<T extends Enum<T>> extends CheckGroup<T> {
public EnumCheckGroup(String id, T[] values) {
super(id);
ListView<T> listview = new ListView<T>("items",
Arrays.asList(values)) {
protected void populateItem(ListItem<T> item) {
item.add(new Check<T>("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
