[DDC-1925] Bug in UnitOfWork and ManyToMany relations

Sun, 29 Jul 2012 10:12:07 +0000

Lets say, I have entity Forum with ManyToMany relations with User.
I need to validate user changes and I use code like

$uow = $this->getDoctrine()~~>getEntityManager()~~>getUnitOfWork();
$uow->computeChangeSets();
$changeSet = $uow->getEntityChangeSet($forum);
if (.... bla-bla-bla....)

{ $em = $this->getDoctrine()->getEntityManager(); $em->persist($forum); $em->flush(); }

Unfortunately, whenever I try to change manyToMany relations - I got error
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '4-4' for key 'PRIMARY'

If I comment uow code - everything works just great.

It looks like bug in UnitOfWork implementation.

Let me know if you need more details from me.
