Form validation for field not possible

[GaiusValerius]

Hi!
If i try to get the messages for a single field i get nothing, but if i get the messages of the form for the field with "$form->getMessagesFor('xyz')" it works correctly.

Code to reproduce:

// Form field
            $element = $this->add(new Element\Mail('mail'));
            $element->addValidator(
                new Validator\PresenceOf(array(
                    'message' => $this->getDi()->get('translator')->query('front.form.error.PresenceOf'),
                ))
            );

// Controller for example
            $mail = $form->get('mail');
            echo '<pre>';
            var_dump($mail->getMessages()); // Wrong - No messages
            var_dump($form->getMessagesFor('mail')); // Correct - PresenceOf Message
            echo '</pre>';
