array(19) {
["fieldName"] => string(10) "privileges"
["joinTable"] => array(4) {
["name"] => string(36) "fsbackend.user_mch_account_privilege"
["schema"] => NULL

Can you try to replace your cache with an `ArrayCache` and see if the problem may come from there?
It would also be interesting to see your bootstrap code and the code you use to interact with the collection.

I'm already using an ArrayCache for my cache.

Also for my bootstrap I'm using this implementation of it : https://github.com/guilhermeblanco/ZendFramework1-Doctrine2.

Here is how i interact with the collection.

$collection->clear();
foreach ($values as $value) {
$collection->add(
$this->_em->getReference(
'Entity\User\Privilege',
$value
));}

... Later on ...
... I have an entity $userAccount with many memberships set to Cascade persist, ....
... and on the membership entity relationship i have my collection ...

$this->_em->persist($userAccount);
$this->_em->flush();

I don't know if it helps but it works if I replace $mapping with $coll on line 181 :

$sourceClass = $this->_em->getClassMetadata(get_class($mapping->getOwner()));

Replaced by :

$sourceClass = $this->_em->getClassMetadata(get_class($coll->getOwner()));

Looks like code coming from the (removed) AssociationMapping class. The fix seems also to be valid. I'm patching this.

Nevermind, I don't think this needs a test. It is just something overlooked during a refactoring. Being handled at DDC-1941

Comment by Marco Pivetta [ 24/Jul/12 ]

Could you please provide the models anyway? It would be interesting to see why the test suite doesn't cover that part
Thank you!

Comment by Jeremie Tom tom [ 24/Jul/12 ]

Ok I attached it. Tell me if you need more informations i didn't upload the full models. But just the parts i thought were relevant.
