Thanks,
I like the $this->field('name', array('id' => $id)); Nice and simple.

You're making the mistake of focusing on the action instead of the
request. In your example, "the whole process" occurs over two separate
requests.
In the validation scenario, I think it's just as well to check if
$this->field('name', array('id' => $id)) returns empty or not.
It's just an example, I know, but your model's method is also
protected, so the controller could not call it.
