Hello, I have an inheritance problem with the following classes

<?php

namespace Proj\Bundle\MyBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;

/****
 * ClassTop
 *
 * @ORM\Table()
 * @ORM\Entity(repositoryClass="Proj\Bundle\MyBundle\Repository\ClassTopRepository")
 * @ORM\InheritanceType("SINGLE_TABLE")
 * @ORM\DiscriminatorColumn(name="aVal", type="string")
 * @ORM\DiscriminatorMap({ "ValOne" = "ClassSubOne", "ValTwo" = "ClassSubTwo", "ValThree" = "ClassSubThree" })
 * 
 */
class ClassTop
{
    .....
}

class ClassSubOne extends ClassTop
{
    ....
}

class ClassSubTwo extends ClassTop
{
    ....
}

class ClassSubThree extends ClassTop
{
    ....
}

When i call findAll method my query is not correct

$entityManager->getRepository('ProjMyBundle:ClassSubOne')->findAll()

the query builded

SELECT field, field2 FROM CLASSTOP WHERE AVAL IN ()

The value for the discriminator column is not passed :(

Thanks for your help
