The following example has User and Address entities, where User has many Addresses (ArrayCollection).


$u = $em->find('Entity\User', $id);
$addresses = $u->getAddresses();
foreach ($addresses as $a) { }  // This line breaks!

The script runs until the foreach loop, then it breaks with a fatal error:

PHP Notice:  Undefined variable: owningAssoc in /home/kaiser/doctrine/doctrine/lib/Doctrine/ORM/Persist

If I uncomment the user creation code in my pastebin example (i.e. create User, Address first), it works as expected (assumingly because everything is in the EM already).

So this bug probably breaks all select-only use cases with collections (which makes it a Blocker in my opinion).

Hm, this is dubious as this is directly and indirectly tested all over the place.

I was unable to reproduce it as of yet. Will keep you updated.

Are you sure you dont have local modifications? The notice looks suspicious and _getSelectEntitiesSql(Array, NULL) does not look correct either. The association should be passed in.

Your patch in DDC-162 is what breaks it.
