Hello Johan,
thank you for your patience and advice :)
I think I'm on the right way now, and the essence for me is that such
special components will also need special models.
In my initial case for a Panel consisting of a TextField and a
Datepicker I solved this by giving the TextField a special model like
this:
class InternalModel extends AbstractModel {
public IModel getNestedModel() {
return DatePickerPanel.this.getModel();
}
public Object getObject(Component component) {
return getNestedModel().getObject(DatePickerPanel.this);
}
public void setObject(Component component, Object object) {
getNestedModel().setObject(DatePickerPanel.this, object);
}
}
I can now add this Panel to the form, and the contents of the
TextField are put in the property defined by the id of the
DatePickerPanel.
