Hi,
Using a Panel should be fine.
Using PropertyModel is also fine.
Assuming there is a CompoundPropertyModel(Person) and Person object has an
Address, and Address has a Street then you should do:
mainModel = new CompoundPropertyModel(new Person());
form = new Form(formId, mainModel);
form.add(new AddressPanel(addressPanelId, new PropertyModel(mainModel,
"address")))
AddressPanel may have a TextField for the Street:
add(new TextField("street"))
or use a random tree structure and use the addressPanel's model:
anIntermediateContainer.add(new TextField("str", new
PropertyModel(AddressPanel.this.getModel(), "street") ))
