symfony - @mailer and @twig in argument of a service error ServiceCircularReferenceException -

i'm trying put twig argument of service have same error :

servicecircularreferenceexception in bootstrap.php.cache line 2129

circular reference detected service "doctrine.orm.default_entity_manager",path: "doctrine.orm.default_entity_manager -> doctrine.dbal.default_connection -> wh.participant_listener -> wh.participant_notification -> twig -> security.authorization_checker -> security.authentication.manager -> fos_user.user_provider.username -> fos_user.user_manager".`

this service.yml file

wh.participant_notification:     class: wh\trainingbundle\notification\notification     arguments: [@mailer, @twig]  wh.participant_listener:     class: wh\trainingbundle\eventlistener\participantlistener     arguments: [@wh.participant_notification]     tags:         - { name: doctrine.event_listener, event: postupdate }         - { name: doctrine.event_listener, event: postpersist } 

my partcicipantlistenerfile

namespace wh\trainingbundle\eventlistener;  use doctrine\orm\event\lifecycleeventargs; use wh\trainingbundle\notification\notification;  class participantlistener {       protected $notification;      public function __construct(notification $notification)     {         $this->notification = $notification;      }   } 

this probleme exist when pass @wh.participant_notificationin arguments of second service

any body has idea ?

thank's lot

i've find solution, not pretty, works :

first pass service container in argument of service

services:  wh.participant_notification:     class: wh\trainingbundle\notification\notification     arguments: ['@service_container']  wh.participant_listener:     class: wh\trainingbundle\eventlistener\participantlistener     arguments: ['@wh.participant_notification']     tags:         - { name: doctrine.event_listener, event: postpersist } 

then in notification.php class :

use symfony\component\dependencyinjection\containerinterface container;  private $container;  public function __construct(container $container) {      $this->container = $container;  }  public function subscribvalidation ($participant) {      $templating = $this->container->get('templating');     $mailer = $this->container->get('mailer');      ...  

i can't create protected var $twig because probleme persiste. repeat, twig service (or template). maybe 1 find better solution ...
