FOSUserBundle Form Registration Overriding - symfony

Question

I've got a problem when I want to override the FOSUserBundle registration Form.
The deal is, in the User entity, some of the users can have a "Sponsor" (a sponsor is a ManyToOne to the same entity), to be more explicit, this is the User Entity :
<?php
namespace Diz\UserBundle\Entity;
use FOS\UserBundle\Entity\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="users")
*/
class User extends BaseUser
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* create FK "sponsor_id" referenced to the id field on the same table
* #ORM\ManyToOne(targetEntity="User")
* #ORM\JoinColumn(name="sponsor_id", referencedColumnName="id", onDelete="SET NULL")
*/
protected $sponsor;
public function __construct()
{
// import FOSUserBundle properities ->
parent::__construct();
}
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set sponsor
*
* #param Dizsurf\UserBundle\Entity\User $sponsor
*/
public function setSponsor(\Dizsurf\UserBundle\Entity\User $sponsor)
{
$this->sponsor = $sponsor;
}
/**
* Get sponsor
*
* #return Dizsurf\UserBundle\Entity\User
*/
public function getSponsor()
{
return $this->sponsor;
}
}
You see ?
Then, to override the RegistrationFormType, I've created one with the official help :
<?php
namespace Diz\UserBundle\Form\Type;
use Symfony\Component\Form\FormBuilder;
use FOS\UserBundle\Form\Type\RegistrationFormType as BaseType;
class RegistrationFormType extends BaseType
{
public function buildForm(FormBuilder $builder, array $options)
{
parent::buildForm($builder, $options);
// add your custom field
$builder->add('sponsor', 'fos_user_username');
}
public function getName()
{
return 'diz_user_registration';
}
public function getDefaultOptions(array $options)
{
return array(
'data_class' => 'Diz\UserBundle\Entity\User', // Ni de modifier la classe ici.
);
}
}
And that's all ! Look like to be pretty simple ! But...
To simply convert the username into a User Entity, FOS advice to use "fos_user_username" in the builder.
Ok for me, but when I test this form :
With a sponsor who does exist, I've got this error "Please enter a password". (of course I've entered the password twice..).
But when I submit a form with an user whose does not exist, the registration form was submitted with success !
Have I done something wrong ?
Thank you for your help ! ;-)

Fixed.
I've just upgraded symfony from 2.0.10 to 2.1 and the problem is not present anymore !
