}Usage:
$entity = new Entity();
$entity->setLabel('labelll');
$friend = new Friend();
$friend->setName('name');
$entity->addFriend($friend);
$entityManager->persist($entity);
$entityManager->flush();Throws ORM/ORMInvalidArgumentException.php:68 "The given entity of type '\TestDoctrine\Entity\Friend' (\TestDoctrine\Entity\Friend@00000000309854b5000000005dfe4c27) has no identity/no id values set. It cannot be added to the identity map".
Because $entity has null id.
Flush after creating new Entity() and before adding $friend to $entity resolve this problem, but it makes many duct tapes.
Doctrine 2.6. Prev version works fine.
