I guess not much if you do the initialize, but it has some issues with
collections (like you need to add to collections instead of setting them
I think). And you will end up doing initialize anyhow so using clone and
a simple compound property model are just as fine plus more simple..

So, what's wrong with using "shadow" models and letting them
eventually write into the real model (which is a LDM) at the very end?

Hi Guys
I've been having a little trouble with hibernate and a multipage wizard, I
finally cracked the nut. And heres my solution:
In the link that refers to the wizard use a loadable detachable model..
Onclick you initialize all proper collections and CLONE the object, after
the wizard are done you merge the clone..
codesniplet:
Link<Event> linkEdit = new Link<Event>("edit",
item.getModel()) {
@Override
public void onClick() {
LoadableDetachableEventModel model=new
LoadableDetachableEventModel(eventRepository,this.getModelObject());
Hibernate.initialize(((Event)model.getObject())
.getLinks());
Hibernate.initialize(((Event)model.getObject())
.getDateStart());
Hibernate.initialize(((Event)model.getObject())
.getDateEnd());
Hibernate.initialize(((Event)model.getObject())
.getTags());
Model<Event> eventModel = new Model<Event>(
(Event) SerializationHelper.clone((Event)
model.getObject()));
CompoundPropertyModel<Event> e = new
CompoundPropertyModel<Event>(
eventModel);
EventWizard newWizard = new EventWizard(eventWizard
.getId(), e) {
@Override
public void onFinish() {
eventRepository.update(eventModel.getObject());
eventWizard.setVisible(false);
}
};
newWizard.setVisible(true);
eventWizard.getPage().addOrReplace(newWizard);
eventWizard = newWizard;
}
};
