Symfony 2 Eingebettete Formulare

Ich bin Einbettung einer form in eine andere form geben, wie so

$builder->add('parent', new \Company\Bundle\Form\UserObjects\AParentType);

Jedoch, wenn ich versuche, und binden die Anforderung an die form

if($request->getMethod() == 'POST') {
      $form->bindRequest($request);
}

Bekomme ich die Fehlermeldung

Abfangbaren Fatal Error: Argument 1 passed to Company\Bundle\Entity\UserObjects\User::setParent() muss eine Instanz des Unternehmens\Bundle\Entity\UserObjects\AParent, array gegeben, aufgerufen /Volumes/Media/Symfony/vendor/symfony/src/Symfony/Component/Form/Util/PropertyPath.php auf der Linie 346 und definiert in /Volumes/Media/Symfony/src/Company/Bundle/Entity/UserObjects/User.php Linie 771

Es scheint, wie die form ist die übergabe der "AParent" Objekt als array statt als eine Einheit. Irgendwelche Ideen?
