我有一个简单的表单，有两个字段，email和name。email在Accounts实体中，name在child实体中：医疗中心

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Validator\Constraints\Email;
use Symfony\Component\Validator\Constraints\NotBlank;

class AccountsMedicalCentersType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('email')
            ->add('name', TextType::class, array(
                'mapped' => false
            ));
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(
            array(
                'validation_groups' => array('emailValidation','Default')
                )
        );
    }
}

我想用验证组验证字段，因为在MedicalCenters实体中，我有一些其他验证，用于其他情况：
帐户实体，验证工作正常：

/**
     * @var string
     *
     * @ORM\Column(name="email", type="string", length=100, nullable=true, unique=true)
     * @Assert\NotBlank(groups={"emailValidation"})
     * @Assert\Email(groups={"emailValidation"})
     *
     */
    protected $email;
 /**
     * @var \MedicalCenters
     *
     * @ORM\ManyToOne(targetEntity="MedicalCenters")
     * @ORM\JoinColumns({
     *   @ORM\JoinColumn(name="medical_centers_id", referencedColumnName="id")
     * })
     *
     * @Assert\Valid
     *
     */
    private $medicalCenters;

MedicalCenters实体，验证组被忽略，返回的错误是第二个错误（地址非空）：

/**
     * @var string
     *
     * @ORM\Column(name="name", type="string", length=300, nullable=true)
     * @Assert\NotBlank(message="name not blank", groups={"emailValidation"})
     *
     */
    private $name;

    /**
     * @var string
     *
     * @ORM\Column(name="address", type="text", length=65535, nullable=true)
     * @Assert\NotBlank(message="address not blank")
     */
    private $address;

我不明白为什么从子实体是不验证只有名称字段，这属于组emailValidation？我做错了什么？
在控制器中，我有：

$form = $this->createForm(
                AccountsMedicalCentersType::class,
                $currentAccount,
                array(
                    'validation_groups' => array(
                        'emailValidation',
                        'Default'
                    )
                )
            );

谢谢
