Re: Ajaxifying FormComponentPanel
When I debug the app, I can see that getObject() is being called for
subgenrefield, only selectedGenre == null. I also put a breakpoint in
convertInput() inside the GenreFieldSwithPanel, but it doesn't pass it.
Shouldn't it use that to determine what the new value of the model will be?

subgenrefield.setOutputMarkupId(true);
subgenrefield.setOutputMarkupPlaceholderTag(true);
form.add(subgenrefield);

final FieldSwitchPanel genrefield = new
GenreFieldSwitchPanel(genre, genres, new
PropertyModelDomainObject(this, selectedGenre));
genrefield.add(new
AjaxFormComponentUpdatingBehavior(onchange) {
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.addComponent(subgenrefield);
}
});
genrefield.setOutputMarkupPlaceholderTag(true);
form.add(genrefield);
The problem is that selectedGenre stays null. So I'm looking for the
cause of that. My guess is that it is because the model isn't updated.
(I did implement convertInput() in GenreFieldSwitchPanel, which
extends FormComponentPanel.)

How do I get it to update properly?
