Strange ClassCastException with DropDownChoice
I'm creating my own DropDownChoice:
private class WeekdayChoice extends DropDownChoice {
public WeekdayChoice(String id,
IModel model) {
super(id, model, new
Model(new DateFormatSymbols().getWeekdays()));
}
@Override
protected boolean
wantOnSelectionChangedNotifications() {

}
@Override

onSelectionChanged(Object newSelection) {
setWeekDayChoice(newSelection);
}
}
... and instantiating it like this:
weeklyLayer.add(weeklyWeekDayChoice = new
WeekdayChoice(weeklyWeekDayChoice,
new
PropertyModel(SubmitForm.this, weekDayChoice)));
However, before the page even paints I get the exception below - any

Re: Strange ClassCastException with DropDownChoice
It looks like your model object is returning a String[], while the class is
expecting a List.

As far as I know, the only exotic stuff we do with serializing is an optimization for page references. But I can't see how that might relate to this. Johan, any ideas? Any chance you could make a test case out of it Xavier? The problem is that without the slightest idea of where it comes from it's difficult to make a test case. The code is public though, so I have a large test case :-) But I'm ok to investigate on my own, if you can give me some hints... Maybe I can switch to another serialization implementation, if I remember well that's something possible, no? You could try that (Objects#setObjectStreamFactory(new WicketObjectStreamFactory()) but since we are now using Java's default serialization, I doubt that would make things better. Indeed, it only failed earlier. But never mind, I've finally found the problem, it was only my fault, bad serialization overriding lost in another component...
