I'm trying to add a password repeat using easy admin bundle but I'm not quite sure how to do it. 
I have these two properties in my entity

```
/**
 * @var string
 *
 * @Assert\NotBlank()
 * @Assert\Length(max="4096")
 */
private $plainPassword;

/**
 * @var string
 *
 * @ORM\Column(type="string", length=64)
 */
private $password;

```

If I add a type: repeated in my config.yml file it just creates two input fields but not a Password type. I believe form should be like this.

```
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('email', EmailType::class)
        ->add('username', TextType::class)
        ->add('plainPassword', RepeatedType::class, array(
            'type' => PasswordType::class,
            'first_options'  => array('label' => 'Password'),
            'second_options' => array('label' => 'Repeat Password'),
            )
        )
        ->add('termsAccepted', CheckboxType::class, array(
            'mapped' => false,
            'constraints' => new IsTrue(),
        )
    );
}

```

I have checked the easy admin bundle documentation but I'm kinda lost how to implement it. <https://github.com/javiereguiluz/EasyAdminBundle/blob/master/Resources/doc/book/7-complex-dynamic-backends.md>

Thanks

* Edit
Okay so I extended the AdminController of `JavierEguiluz\Bundle\EasyAdminBundle\Controller\AdminController`

```
public function createNewForm($entity, array $entityProperties)
{
    $userForm = parent::createNewForm($entity, $entityProperties);

    if ($entity instanceof User) {
        $userForm->remove('password');
        $userForm->add('plainPassword', RepeatedType::class, array(
            'type' => PasswordType::class,
            'first_options' => array('label' => 'Password'),
            'second_options' => array('label' => 'Re-enter Password')
        ));
    }

    return $userForm;
}

```

But now when I try to insert / submit the form, sql error password cannot be null.
