Doctrine2 dynamic table name for the object

Question

I am trying to add a dynamic table name for some of my objects.

I read this post [Dynamic names of tables / entities in Doctrine 2] [1] [1]: Dynamic names of tables / entities in Doctrine 2 , and this story about the doctrine listener [doctrinaire-listener] [2] [2]: http: //doctrine-orm.readthedocs.org/en/latest/reference/events.html

So here is how I do it:

I created an object with a wildcard in its table name:

<?php

namespace DD\MyBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * SiteElec
 *
 * @ORM\Table(name="site_x_elec")
 * @ORM\Entity
 * @ORM\HasLifecycleCallbacks
 * @ORM\EntityListeners({"DD\MyBundle\Entity\Listener\SiteElecListener"})
 */
class SiteElec
{
    I skip properties with getters and setters

}

Next, I performed a listen for this object:

<?php

namespace DD\MyBundle\Entity\Listener;

use DD\UserBundle\Entit\User;
use Doctrine\ORM\Event\LoadClassMetadataEventArgs;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;

/**
 * Listener pour l'entité siteElec.
 */
class SiteElecListener {


private $_tableName = null;
protected $token_storage;
protected $user;

public function getTableName() {
    return $this->_tableName;
}

public function setTableName($tableName) {
    $this->_tableName = $tableName;
    return $this;
}

public function __construct(TokenStorageInterface $token_storage) {

    $this->token_storage = $token_storage;

    if($token_storage->getToken() != null){

    }
}

/*
 * @ORM\LoadClassMetadata
 * @param LoadClassMetadataEventArgs $eventArgs
 */
public function loadClassMetadata(LoadClassMetadataEventArgs $args) {

    //$this->user = $this->token_storage->getToken();
    //var_dump($this->token_storage);

    $classMetadata = $args->getClassMetadata();
    $table = $classMetadata->table;
        var_dump($classMetadata);
//        $table['name'] = 'site_'.$this->user->getSite()->getId().'_elec';
//        $classMetadata->setPrimaryTable($table);
}

}

Next, I declare my listener in the configuration file:

    dd.entity_listener.site_elec:
    class:      DD\MyBundle\Entity\Listener\SiteElecListener
    arguments:  
        - "@security.token_storage"
    tags:
        - { name: doctrine.event_listener, event: loadClassMetadata }

If I look at $ classMetadata var , I only have my custom entity and related object, but not my SiteElec object

1) (name= "NULL" )

<?php

namespace DD\MyBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * SiteElec
 *
 * @Table(name="NULL")
 * @ORM\Entity
 */
class SiteElec { ... }

2)

$EM
  ->getClassMetadata('DD\MyBundle\Entity\SiteElec')
  ->setTableName($DYNAMIC_TABLE_NAME);

3)

$result = $EM
  ->getRepository('DD\MyBundle\Entity\SiteElec')
  ->findBy(['id' => $SOME_ID]);
