Проверка Symfony2 не работает, когда Entity Relationships / Associations

контроллер

public function indexAction(Request $request) { $user = $this->container->get('security.context')->getToken()->getUser(); $owner = $user->getId(); $first = new First(); $first->setOwner($owner); $second = new Second(); $second->setOwner($owner); $second->setFirst($first); $form = $this->createForm(new SecondType(), $second); if ($request->getMethod() == 'POST') { $form->bindRequest($request); if ($form->isValid()) { $em = $this->get('doctrine')->getEntityManager(); $em->persist($first); $em->persist($second); $em->flush(); } } return $this->render('MySampleBundle:Home:index.html.twig', array( 'form' => $form->createView(), )); } 

ORM Yaml

Форма / тип

 class FirstType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add('title', 'text'); } public function getDefaultOptions(array $options) { return array( 'data_class' => 'My\SampleBundle\Entity\First', ); } public function getName() { return 'first'; } } class SecondType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add('first', new FirstType()); $builder->add('review', 'textarea'); } public function getName() { return 'second'; } } 

Validation.yml

 My\SampleBundle\Entity\First: properties: title: - NotBlank: ~ - MinLength: 2 My\SampleBundle\Entity\Second: properties: review: - NotBlank: ~ - MinLength: 14 Во- My\SampleBundle\Entity\First: properties: title: - NotBlank: ~ - MinLength: 2 My\SampleBundle\Entity\Second: properties: review: - NotBlank: ~ - MinLength: 14 

Созданная форма работает нормально. Однако только проверка не работает нормально.

Если он выполняет индивидуально, проверка будет работать нормально.

 $form = $this->createForm(new FirstType(), $first); 

Однако, если он находится в состоянии Entity Relationships / Associations, первая проверка не будет работать. Свойство Title First в одном символе будет зарегистрировано.

Как я могу это достичь?
