Hi Rich,
You always need a domain model to process the data of the form. What
you can do though is compose a form of different forms acting on
different domain models.
I.e.
$form = new Form('base_form', $baseModel);
$dispatcher->notify('...');
and in the event handler you can add a subform
$behaviour = new MyBehaviour();
$behaviourForm = new Form('my_behaviour', $behaviour);
$behaviourForm->add(new TextField('behaviourProperty'));
$form->add($behaviourForm);
class MyBehaviour
{
/** constraints defined here */
protected $behaviourProperty;
}
