[DDC-2317] [UnitOfWork] Entity in identityMap but not present in entityIdentifiers

Tue, 26 Feb 2013 08:35:23 +0000

I'm using symfony 2.1.8 and sonata/admin-bundle
I have a quite complex entity mapping.

A Competence has many CompetenceAction (superclass)
CompetenceActionBuff is a subclass of CompetenceAction and has exactly one buff (selectable in the form by an 'entity' field).

When i want to edit a Competence, i have the following error message about the Buff entity linked to the CompetenceActionBuff:
"Entities passed to the choice field must be managed. [...]"
The exception is raised in Symfony/Bridge/Doctrine/Form/ChoiceList/EntityChoiceList.php at line 412

I've added some debug code in the EntityManager::contains() method and it shows that my entity is in the entityMap but his oid is not in the keys of entityIdentifiers making the call to UnitOfWork::isInIdentityMap() return false at line 1505.

When submitting the form, there is no problems. All the entities are correctly created in the database. The exception is thrown only when i want to edit the Competence object. Saying that the Buff object is not managed when it was first loaded from the database... strange, no?

Finally, i tried to comment the test

if (!$this->em->contains($entity)))

in EntityChoiceList::getIdentifierValues() and everything seemed to work properly.
