How can translatable in many-to-many relationship in Doctrine2? Symfony2 - symfony

Question

I've used Translatable with a personal translation; I've implemented PysTranslationand I've used ORM query hint in PysRepository. All of this works fine, the problem has been when I've translated the entity Genero. This entity has a many-to-many relationship with Pys entity and the above method doesn't work. How I can translate the $genNombre attribute of Generoentity?

class Pys

public function addTranslation(PysTranslation $t)

if (!$this->translations->contains($t)) {

}
This is Genero
<?php
namespace Filmboot\PYSBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
use Gedmo\Mapping\Annotation as Gedmo;
/**

* inverseJoinColumns={#ORM\JoinColumn(name="PYS_ID", referencedColumnName="PYS_ID")}
* )
*/
private $peliculas;
This is PysTranslation
/**
* #ORM\Entity
* #ORM\Table(name="pys_translation", uniqueConstraints={#ORM\UniqueConstraint(name="lookup_unique_idx", columns={"locale", "object_id", "field"})})
*/
class PysTranslation extends AbstractPersonalTranslation
{
/**
* Convinient constructor
*
* #param string $locale
* #param string $field
* #param string $value
*/
public function __construct($locale, $field, $value)
{
$this->setLocale($locale);
$this->setField($field);
$this->setContent($value);
}
/**
* #ORM\ManyToOne(targetEntity="Pys", inversedBy="translations")
* #ORM\JoinColumn(name="object_id", referencedColumnName="PYS_ID", onDelete="CASCADE")
*/
protected $object;
}
This is PysRepository
class PysRepository extends EntityRepository
{
public function findPeliculas()
{
$em = $this->getEntityManager();
$consulta = $em->createQuery('
SELECT p, a, d, g, pr, v
FROM PYSBundle:Pys p
JOIN p.actores a JOIN p.director d JOIN p.generos g JOIN p.premios pr JOIN p.votaciones v
ORDER BY p.pysTitulo ASC
');
return $consulta->setHint(\Doctrine\ORM\Query::HINT_CUSTOM_OUTPUT_WALKER, 'Gedmo\\Translatable\\Query\\TreeWalker\\TranslationWalker')->getResult();
}
/**
*
* #param string $pysStr El slug de la película
*/
public function findPys($pysStr)
{
$em = $this->getEntityManager();
$consulta = $em->createQuery('
SELECT p, a, d, g, pr, v

$consulta->setParameter('pysStr', $pysStr);
return $consulta->setHint(\Doctrine\ORM\Query::HINT_CUSTOM_OUTPUT_WALKER, 'Gedmo\\Translatable\\Query\\TreeWalker\\TranslationWalker')->getSingleResult();
}
}

I've solved the problem by adding this line in Genero entity annotations:
/**
* Genero
*
* #ORM\Table(name="genero")
* #ORM\Entity
* #Gedmo\TranslationEntity(class="Filmboot\PYSBundle\Entity\GeneroTranslation")
*/
class Genero
