Hi,

Using doctrine/orm 2.8.4 (got same issue with all 2.8.x tags)

I have an entity :

class UmbrellaFile
{
    /**
     * @var int|null
     * @ORM\Column(type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    public $id;

    /**
     * @var string
     * @ORM\Column(type="string", length=255, nullable=false)
     */
    public $configName;

 [...] Some other simple properties
}

Somewhere on code, i have following code :
$this->em->remove($file);

If i dump my entity, before call $this->em->remove(...);, i got :

Proxies\__CG__\Umbrella\CoreBundle\Entity\UmbrellaFile^ {#751
  +__isInitialized__: false
  +_uploadedFile: null
  +_deleteSourceFile: true
  +id: 16
   …2
}

I have an EventSubscriberInterface listening on 'postRemove' events:

  public function postRemove(LifecycleEventArgs $args): void
  {
      $entity = $args->getObject();

        if (!$entity instanceof UmbrellaFile) {
            return;
        }
        $entity->configName; // crash here
  }

At runtime got an exception at line $entity->configName:

request.CRITICAL: Uncaught PHP Exception ErrorException: "Warning: Undefined array key "id"" at /home/acantepie/projects/umbrella-admin-demo/vendor/doctrine/orm/lib/Doctrine/ORM/Utility/IdentifierFlattener.php line 94 {"exception":"[object] (ErrorException(code: 0): Warning: Undefined array key \"id\" at /home/acantepie/projects/umbrella-admin-demo/vendor/doctrine/orm/lib/Doctrine/ORM/Utility/IdentifierFlattener.php:94)"} []

in vendor/doctrine/orm/lib/Doctrine/ORM/Utility/IdentifierFlattener.php (line 94)
in vendor/doctrine/orm/lib/Doctrine/ORM/Proxy/ProxyFactory.php -> flattenIdentifier (line 156)
in var/cache/dev/doctrine/orm/Proxies/__CG__UmbrellaCoreBundleEntityUmbrellaFile.php -> Doctrine\ORM\Proxy\{closure} (line 74)
in var/cache/dev/doctrine/orm/Proxies/__CG__UmbrellaCoreBundleEntityUmbrellaFile.php -> __invoke (line 74)
UmbrellaFile->__get('configName')
in /home/acantepie/projects/umbrella/Bundle/CoreBundle/src/Component/UmbrellaFile/UmbrellaFileSubscriber.php (line 34)

I can resolve issue if i force orm to initialize entity :

         $file->configName; // orm will intialize entity
         $this->em->remove($file);

From the docs:

Note that the postRemove event or any events triggered after an entity removal can receive an uninitializable proxy in case you have configured an entity to cascade remove relations. In this case, you should load yourself the proxy in the associated pre event.

This sounds a bit like what is happening to you, doesn't it?

Careful, "comprehensive" is a faux-ami . But you are right, there could be better DX here.
