      Description

      After updating to from symfony 2.0 to symfony 2.1, creating a new mapping did not work when using \Doctrine\ORM\Mapping\ClassMetadata::mapOneToMany().

      The code used was:

              /** @var $metadata \Doctrine\ORM\Mapping\ClassMetadata */
              $metadata = $this->getDoctrine()->getEntityManager()->getClassMetadata('SecretSecretBundle:Deal');
      
              if (!array_key_exists('rolap', $metadata->getAssociationMappings())) {
                  // use a temporary join mapping
                  $metadata->mapOneToMany(array(
                      'targetEntity' => 'Secret\SecretBundle\Entity\RolapDealP1m',
                      'fieldName' => 'rolap',
                      'mappedBy' => 'deal',
                  ));
              }
      

      A manyToOne mapping from RolapDealP1m to Deal was already created in the RolapDealP1m entity class.

      Then, a query using the queryBuilder was created like this:

      $qb=$repo->createQueryBuilder('Deal');
      $qb
          ->join('Deal.rolap', 'Rolap')
      [additional joins]
          ->select(
              array(
                  'Deal.number number',
                  'Deal.product productName',
      [additional fields]
              )
          )
      [additional where and group by]
      ;
      

      The problem occurs, when doing a simple

      $qb->getQuery()->getResult();
      

      On symfony 2.0 using doctrine 2.2.2 it worked fine, the result was returned.
      On symfony 2.1 using doctrine 2.3.2 and 2.2.2 an error occurs:

      Notice: Undefined index: rolap in /var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Internal/Hydration/ObjectHydrator.php line 366
      

      As a workaround, we added the OneToMany mapping to the Deal Entity instead of using a temporary mapping. This worked fine with symfony 2.1/doctrine 2.3.2.

      We think there has been a regression when trying to create temporary mappings.
