Hello. I have a problem with two diffents copy of em

<?php
namespace App\Listener;
use Doctrine\ORM\EntityManagerInterface;

class FirstListener
{
    public function __construct(EntityManagerInterface $entityManager)
    {
        dump('create FirstListener');
        dump($entityManager);
    }
}

<?php
namespace App\Controller;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\HttpFoundation\Response;

class LuckyController
{
    public function number(EntityManagerInterface $entityManager)
    {
        dump('number action invoke');
        dump($entityManager);

        return new Response(
            '<html><body>hello</body></html>'
        );
    }
}

service.yaml:

    App\Listener\FirstListener:
      tags:
      - { name: doctrine.orm.entity_listener }

result:
image

why ?
for investigation I use:
composer create-project symfony/skeleton blog

Can you create a small example application that allows to reproduce your issue?

very simple. Based on symfony skeleton

Hmm I think this case should result in a ServiceCircularReferenceException?

If you mark your FirstListener service as lazy: true + require symfony/proxy-manager-bridge it should behave correctly in the meantime.

Nope. You can see service.yaml (first post) Very simple.
I used xdebug for investigation this problem: symfony create second container

@dmaicher

Nope.

yes currently it does not throw any ServiceCircularReferenceException 😊 But I think it should. Because while building the entity manager service it creates your listener service (which itself needs the entity manager).

I think there is no 'Circular Reference'. Simple injection for listener as service.
Second: It's problem actual only for Entity Manager.

For me this is a circular reference.

EntityManager -> EntityListenerResolver -> FirstListener -> EntityManager

Waiting for @nicolas-grekas to have a look and confirm

In my case: I use service which use EntityManager.
Thats mean - I can't use any services with EntityManager included.

That's not correct. Your service is a bit special because its tagged as doctrine.orm.entity_listener.

I've experienced the same issue using the factory method:

@doctrine.orm.default_entity_manager::getRepository($entityName)

To solve this i had to switch to @doctrine.orm.container_repository_factory::getRepository($EntityManager, $EntityName)

repository.user:
    class: Infrastructure\Persistence\DoctrineORM\Repository\UserRepository
    factory: ["@doctrine.orm.container_repository_factory", getRepository]
    arguments:
      - '@doctrine.orm.default_entity_manager'
      - 'Domain\Entity\User'

Refer to: stackoverflow question

I have the same issue.

I have 2 services, each getting a different instance of the manager. (spl_object_hash different) Both are using simple constructor injection, autowired, and type hinted as Doctrine\ORM\EntityManagerInterface.

These manager have different units of work, so have different managed entities.

@ro0NL Thank you, this fixed my issue.

The original problem in this issue seem a bit older, so it should be different as @nicolas-grekas pointed out in the PR.
