Symfony2 Doctrine ODM implements class form validation

I have a mongodb doctrine document that I have converted into a form. The document contains two emebedOne documents, which are also in the form. The main document is checked, but the embedded documents are not. I use custom statements, but I don't think this is important.

Document

    class AccountRecord {
    / **
     * @MongoDB \ Id
     * /
    private $ id;

    / **
     * @MongoDB \ Field (type = "BimcoreEmail")
     * @Assert \ Email
     * @Assert \ NotNull
     * @CustomAssert \ BimcoreEmail
     * /
    private $ email;

    / **
     * Access Admin
     * 
     * @MongoDB \ Boolean
     * /
    private $ access_admin = 0;


    / ** @MongoDB \ EmbedOne (targetDocument = "vidAccountSettings") * /
    private $ vid;
   }

assert .

/** @MongoDB\EmbeddedDocument */
class vidAccountSettings {
    /**
     * Share section path
     *
     * 
     * @MongoDB\Field(type="Url")
     * @CustomAssert\Url
     */
    private $sharePath;
}

class AccountEditFormType extends AbstractType
{
    /**
     * Builds the embedded form representing the user.
     *
     * @param FormBuilder $builder
     * @param array       $options
     */
    public function buildForm(FormBuilder $builder, array $options){
        $builder
            ->add('prefix', 'hidden', array('required' => false))
            ->add('vid.access', 'checkbox', array('required' => false))
            ->add('vid.googleAnalytics', 'text', array('required' => false))
            ->add('vid.liveRail', 'text', array('required' => false))
            ->add('vid.sharePath', 'url', array('required' => false))
            ;
    }

    public function getDefaultOptions(array $options)
    {
        return array(
            'intention'  => 'editAccount',
            'cascade_validation' => true,
        );
    }

    public function getName()
    {
        return 'bimfs_account_creation';
    }



}

class AccountEditFormHandler
{
    protected $request;
    protected $userManager;
    protected $form;

    public function __construct(Form $form, Request $request, BimcoreAccountManager $accountManager)
    {
        $this->form = $form;
        $this->request = $request;
        $this->accountManager = $accountManager;
    }

    public function process($account)
    {
        // set the data in the form for the current account.
        $this->form->setData($account);

        if ('POST' === $this->request->getMethod()) {

            $this->form->bindRequest($this->request);
            if ($this->form->isValid()) {
                $this->onSuccess($account);
                return true;
            } else {
            }
        }

        return false;
    }


    protected function onSuccess(BimcoreAccountRecord $account)
    {
        // update the account data.
        $this->accountManager->updateAccount($account);
    }
}
