Jira issue originally created by user mastir:

Sometimes doctrine query results proxy objects, even if them loaded directly. Proxy class overriding __clone method, so i can't reset id fields for it.I used another method "__clone_again_for_random_proxified_entity" to reset image id, but i'm sure its not the way this shuld work.
My code as example:

             $imgs = $this->getService('doctrine')->getQueryBuilder()
                    ->select('i')
                    ->from('Page\\Image', 'i')
                    ->where('i.page=:p')
                    ->getQuery()
                    ->setParameter('p',$source)
                    ->getResult();
                foreach($imgs as $img){
                    $copy = clone $img;
                    if(is*callable([$img, '_*isInitialized'])){ //is a proxy
                        $copy->*_clone_again_for_random_proxified*entity();
                    }
                    $entity->addPart($copy);
                }

i wasted half of day to catch collction with proxified entity (i think its loaded some where before as a proxy and then initialized on query)
i think its easy to fix by adding parent::**clone call on a proxy objects and avoid this kind of bugs. Thanks.

parent::**clone should actually be in the proxies. If that's not the case, then please write a test case against https://github.com/doctrine/common

Manual proxy regeneration solved this problem. Thanks a lot.
