For 

return array($kevin, $anne);

you receive ContextErrorException:

Catchable Fatal Error: Argument 3 passed to Sonata\AdminBundle\Util\AdminObjectAclData::__construct() must implement interface Traversable, array given, called in C:\_\xampp\htdocs\_projects\laas\git\vendor\sonata-project\admin-bundle\Controller\CRUDController.php on line 1027 and defined
500 Internal Server Error - ContextErrorException

Also maybe $container can be replaced by $this->container on line 689?

Thanks!
