How do you get the selected items in a Wicket ListMultipleChoice?

Question

I'm using a ListMultipleChoice component in wicket and I want to get the selected items. It seems that isSelected is protected so I cannot use it. How do I get the selected items?

Answer 1

You must bind your list with data and ListMultipleChoice as in Example

public MyForm(String id, IModel model, IFeedback feedback) {
List choices = new ArrayList();
choices.add("foo");
choices.add("bar");
MultiListChoice lc = new MultiListChoice("myMultiListChoice", new PropertyModel(model, "foobarList"), choices);
add(lc);
...

}
