DDC-2317: [UnitOfWork] Entity in identityMap but not present in entityIdentifiers #3021

Jira issue originally created by user rpiotaix:

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.

Can you please reproduce this in an insulated environment (without symfony forms involved)?


Comment created by rpiotaix:

By doing this, all work properly, the exception is not thrown:

```$competence = $this->getRepo(\Sistearth\JeuBundle\Entity\Competence\Competence::REPO)->find(1);
$buff = $competence->getActions()[0]->getBuff();

$em = $this->getDoctrine()->getEntityManager();

throw new \Exception("Not in EntityManager");

but if i add this after:

$form = $this->createForm(new \Sistearth\JeuBundle\Form\Competence\CompetenceType(), $competence);

then, the exception "Entities passed to the choice field must be managed. Maybe persist them in the entity manager?" is back.

I'll try to do some others tests...

[~rpiotaix] the problem is exactly the last bit :) Doctrine has no forms, so you will have to create a small script that reproduces the problem without symfony, starting from:

php composer.phar require doctrine/orm:dev-master@dev


Comment created by rpiotaix:

Bug found!

In the form type CompetenceActionBuffType, i marked the field buff with array('by*reference"=>false). If byreference is set to false, the modelData is cloned (here the Buff proxy) at line 349 in Form.php.
And, by cloning the object, the spl
object*hash of the clone is different from the original one's.

Is this a symfony Form component bug or a doctrine one?

[~rpiotaix] this is a problem of symfony forms, please report it on the symfony issue tracker (check if there's a similar open issue first) at
