Entity listener preUpdate or postUpdate methods not called symfony 4.2

[chernoubi]

i want to use entity listener on Site entity this is my code for Site.php

       namespace App\Entity;

    use Doctrine\Common\Collections\ArrayCollection;
    use Doctrine\Common\Collections\Collection;
    use Doctrine\ORM\Mapping as ORM;
    use Symfony\Component\Validator\Constraints as Assert;

    /**
     * @ORM\Entity(repositoryClass="App\Repository\SiteRepository")
     * @ORM\EntityListeners({"App\Entity\Listener\SiteListener"})
     * @ORM\HasLifecycleCallbacks()
     */
    class Site
    {
        /**
         * @ORM\Id()
         * @ORM\GeneratedValue()
         * @ORM\Column(type="integer")
         * @Assert\Type("int")(groups={"inputsite"})
         */
        private $id;

        /**
         * @ORM\Column(type="string", length=255)
         * @Assert\NotBlank(groups={"inputsite"})
         */
        private $intitule;
etc ...

SiteListener.php

<?php

namespace App\Entity\Listener;

use App\Entity\Site;
use App\Repository\SiteRepository;


class SiteListener
{

    public function prePersist(Site $site, LifecycleEventArgs $args)
    {
        echo 'prePersist';

    }

    public function preUpdate(Site $site, LifecycleEventArgs $args)
    {
      echo 'preUpdate';

    }

}

and my service is declared like

site_listener:
    class: App\Entity\Listener\SiteListener
    arguments: ~
    tags:
        - { name: doctrine.orm.entity_listener }

**when i try to insert new site its OK!

My probleme is when i want to update an existant site ,prePersist method is always called instead of preUpdate ,and nothing is updated and my site was saved like a new enregistement in BDD with a new id**
-If i remove the tag key from my service i can add/update my Site but no event is fired

/**
 * @Route("/default", name="default")
 */
public function index()
{


    $siteInput= $this->getDoctrine()->getRepository(Site::class)->find(169);
    $siteInput->setIntitule('setIntitule')->setDomaine('setDomaine')->setIsEnabled(true);

    $this->getDoctrine()->getManager()->persist($siteInput);
    $this->getDoctrine()->getManager()->flush();

    die('fin');
}

Thx :)

@chernoubi how come you closed this issue? Were you able to resolve it? If so could you explain what the problem was and how you dealt with it please?

[maguramarkian]

maybe problem is on line $this->getDoctrine()->getManager()->persist($siteInput);

You don't need persist object if you need update it
