> add(group);
>
> ListView userAddresses = new ListView("addresses",

> CompoundPropertyModel(item.getModelObject()));
> item.add(new Radio("is_default"));
> item.add(new Label("address.street"));
> item.add(new Label("address.zip"));
> item.add(new Label("address.city"));
> item.add(new Label("address.country"));

> My Problem is that i need to select an address by default based on the

> to the is_default value when switching back and forth between wizard-steps.
>
> I've already tried the solution described in the wiki for setting default
> values to radiogroups (http://cwiki.apache.org/WICKET/using-radiogroups.html),
> but this resets the selected radiobutton when switching wizard pages to the
> default value, so the wizard doesn't "remember" if a default option
> has been changed by the user.
>
> I'd appreciate any hints on how to solve this one.
