That is because on the wizard component you define a
CompoundPropertyModel, and you ask the model of a wizardstep
(RegNumberStep), which is a *child* of that wizard (a direct child,
with id 'view'). As RegNumberStep does not have an explicit model set
itself, it will use the parent's CompoundPropertyModel to get the
model value, but with it's own id as a property expression.
In the same fashion:
setModel(new CompoundPropertyModel(person));
add(new TextField("name"));
will have the effect that the textfield works on property name of person.
A solution is to do this instead: findParent(Wizard.class).getModelObject()
Or... you could expliciltly pass in references to the model object.
The NewUserWizard for example does this (see the user var/ getUser
method). If you don't want to use nested classes like that, you'd have
to explicitly pass the person object or expose it in another way.
Hope that helped,
Eelco
