Ok, I have a class 'Person' with an'Address-Property. My Form-object has a
simple Model wrapping a Person-object. The constructor creating the Panel
with the form contains these lines:
form = new Form<Person>("form", new Model<Person>());
personFormComponent = new
PersonFormComponent<Student>("personFormComponent", form.getModel());
addressFormComponent = new
AddressFormComponent<Address>("addressFormComponent", new
PropertyModel<Address>(this.form.getModel(), "address"));
form.add(personFormComponent);
form.add(addressFormComponent);
After creation of this Panel I call form.setModelObject(...). So the model
ist not empty. The PersonFormComponent works well as it only sets some
String-Properties of the Person-Object. But I have trouble with the
AddressFormComponent which looks like this:
public class AddressFormComponent<T extends Address> extends
FormComponentPanel<T> {
protected TextField<String> cityField, postcodeField, streetField;
protected IModel<T> model;
public AddressFormComponent(String id, IModel<T> model) {
super(id, model);
// Model
this.model = model;
// Straße
streetField = new TextField<String>("streetField", new
PropertyModel<String>(model, "street"));
streetField.setRequired(true);
streetField.add(StringValidator.lengthBetween(0, 100));
// PLZ
postcodeField = new TextField<String>("postcodeField", new
Model<String>(""));
postcodeField.setRequired(true);
// Stadt
cityField = new TextField<String>("cityField", new
Model<String>(""));
cityField.setRequired(true);
cityField.add(StringValidator.lengthBetween(0, 50));
this.add(streetField);
this.add(postcodeField);
this.add(cityField);
}
}
After submitting the whole form (with an AjaxButton) the Address-Property of
my Person-Object ist null. Perhaps I did not use the Models correctly ...?
