Put in one case I Noticed that all the WizardSteps uses the same
backingbean, so I started to think about using a compoundpropertymodel that
I set to the Wizard in its constuctor. Something like this:
public MywizardConstuctor(String id){
super(id);
CompoundPropertyModel<BackingBean> formModel = new
CompoundPropertyModel<BackingBean>(new BackingBean());
setDefaultModel(formModel);
WizardModel wizardmodel = new WizardModel();
wizardmodel.add(new WizardStep1());
wizardmodel.add(new WizardStep2());
init(wizardmodel);
}
TextField firstnameTF = new TextField<String>("firstName",new
PropertyModel<String>(getDefaultModel(), "nestedobj.firstname"));
But I cant make it work! The former TextField code works, but the one with
getDeafultModel() doesnt. The defaultModel is null. I tryid to
findParent(Wizard.class).getDefaultModel() but it failes, probably because
the Step has not been added to the WizardModel yet.
Can anyone explain to me why 'new TextField<String>("firstName")' works?

Looks like you're using 1.4, but I can explain you how I'm doing it in 1.3:
In the wizard: IModel model = new CompoundPropertyModel(this);setModel(model); // i dont have a setDefaultModel() - Maybe that's the difference?
WizardModel wizardModel = new WizardModel();
wizardModel.add(new MyStep(model));
Like that I already have the model in my step (MyStep)
There I'm doing:
setModel(model); // again, I dont have a setDefaultModel()
add(new TextField("my.id", new PropertyModel(getModel(), "propertyName"));
In your example, you're not passing the model to the steps - that's why
it cannot be there.
The above example works for me in Wicket 1.3.x, so I think it shouldn't be that different in your case.
