Try this logic:

In the controller:

if (!$this->data) {
 $this->set('referer', $this->referer($default));
} else {
  if ($this->Model->save()) {
  $this->redirect ($this->data['_App']['referer']);
}
}

in the view:
...
echo $form->input('_App.referer', array('value' => $referer, 'type' =>
'hidden'));
...

Personally, I always add a referer to all forms to use for exactly the
purpose you highlight.
