Jira issue originally created by user rickdt:

The discriminator value column is lost after querying on an object.

Look at case DDC-149 for detailled entities.

Before this, $rev_type field equal "HEAD". After, it is empty string.

$qb = new \Doctrine\ORM\QueryBuilder($em);
        $qb->select('fna')
            ->from('Entity\FNA', 'fna')
            ->andwhere($qb->expr()->eq('fna.id', ':fna_id'));
        $qb->setParameter('fna_id', 1);
        $query = $qb->getQuery();

        $fna = $query->getSingleResult();
        $em->flush();

Comment created by rickdt:

This problem occurs only if a field is set with the same name that the discriminator field.

That was my mistake.
