Listener "SoftDeleteableListener" was not added to the EventManager

Question

I followed the this example to test softdeletable extension on my project running Symfony 2.1.0-DEV.

I configured my config.yml like below:

orm:
    auto_generate_proxy_classes: %kernel.debug%
    auto_mapping: true
    filters:
          softdeleteable:
            class: Gedmo\SoftDeleteable\Filter\SoftDeleteableFilter
            enabled: true
    mappings:
        translatable:
            type: annotation
            alias: Gedmo
            prefix: Gedmo\Translatable\Entity
            # make sure vendor library location is correct
            dir: "%kernel.root_dir%/../vendor/gedmo/doctrine-extensions/lib/Gedmo/Translatable/Entity"
        loggable:
            type: annotation
            alias: Gedmo
            prefix: Gedmo\Loggable\Entity
            dir: "%kernel.root_dir%/../vendor/gedmo/doctrine-extensions/lib/Gedmo/Loggable/Entity"
        tree:
            type: annotation
            alias: Gedmo
            prefix: Gedmo\Tree\Entity
            dir: "%kernel.root_dir%/../vendor/gedmo/doctrine-extensions/lib/Gedmo/Tree/Entity"   

My controller action:

/**
 * @Route("/del", name="del_article")
 */
public function delAction() {
    $em = $this->getDoctrine()->getEntityManager();

    $article = $em->find('Article', 3);
    $em->remove($article);
            $em->flush();
    die('ok');
}

When I run the code, it always show the exception: Listener "SoftDeleteableListener" was not added to the EventManager!

After some time spent with debugging, I found that the class SoftDeleteableFilter has function getListener():

protected function getListener()
{
    if ($this->listener === null) {
        $em = $this->getEntityManager();
        $evm = $em->getEventManager();

        foreach ($evm->getListeners() as $listeners) {
            foreach ($listeners as $listener) {
                if ($listener instanceof SoftDeleteableListener) {
                    $this->listener = $listener;

                    break 2;
                }
            }
        }

        if ($this->listener === null) {
            throw new \RuntimeException('Listener "SoftDeleteableListener" was not added to the EventManager!');
        }
    }

    return $this->listener;
}

However $listeners property has no SoftDeleteableListener item, but it has other listeners, such as

• Gedmo\Tree\TreeListener
• Gedmo\Sortable\SortableListener
• Gedmo\Sluggable\SluggableListener
• Gedmo\Loggable\LoggableListener
• Gedmo\Timestampable\TimestampableListener
• Gedmo\Translatable\TranslatableListener

Which are generated from loadClassMetadata. I think it might generate from my doctrine_extensions.yml service listener:

services:
    extension.listener:
        class: Infinitz\UserBundle\Listener\DoctrineExtensionListener
        calls:
            - [ setContainer, [ @service_container ] ]
        tags:
            - { name: kernel.event_listener, event: kernel.request, method: onLateKernelRequest, priority: -10 }
            - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }
    gedmo.listener.tree:
        class: Gedmo\Tree\TreeListener
        tags:
            - { name: doctrine.event_subscriber, connection: default }
        calls:
            - [ setAnnotationReader, [ @annotation_reader ] ]

    gedmo.listener.translatable:
        class: Gedmo\Translatable\TranslatableListener
        tags:
            - { name: doctrine.event_subscriber, connection: default }
        calls:
            - [ setAnnotationReader, [ @annotation_reader ] ]
            - [ setDefaultLocale, [ %locale% ] ]
            - [ setTranslationFallback, [ false ] ]

    gedmo.listener.timestampable:
        class: Gedmo\Timestampable\TimestampableListener
        tags:
            - { name: doctrine.event_subscriber, connection: default }
        calls:
            - [ setAnnotationReader, [ @annotation_reader ] ]

    gedmo.listener.sluggable:
        class: Gedmo\Sluggable\SluggableListener
        tags:
            - { name: doctrine.event_subscriber, connection: default }
        calls:
            - [ setAnnotationReader, [ @annotation_reader ] ]

    gedmo.listener.sortable:
        class: Gedmo\Sortable\SortableListener
        tags:
            - { name: doctrine.event_subscriber, connection: default }
        calls:
            - [ setAnnotationReader, [ @annotation_reader ] ]

    gedmo.listener.loggable:
        class: Gedmo\Loggable\LoggableListener
        tags:
            - { name: doctrine.event_subscriber, connection: default }
        calls:
            - [ setAnnotationReader, [ @annotation_reader ] ]         

So I tried to add following:

gedmo.listener.softdeleteable:
    class: Gedmo\SoftDeleteable\SoftDeleteableListener
    tags:
        - { name: doctrine.event_subscriber, connection: default }
    calls:
        - [ setAnnotationReader, [ @annotation_reader ] ]

But it still shows Listener "SoftDeleteableListener" was not added to the EventManager!

Do I need to add an listener which instance of SoftDeleteableListener?

Couldn't solve problem because of unclear answer.

To add softdeletable behaviour to your project add following lines to your config.yml

orm
  ..
  filters:
    softdeleteable:
      class: Gedmo\SoftDeleteable\Filter\SoftDeleteableFilter
      enabled: true

services:
  ..
  gedmo.listener.softdeleteable:
    class: Gedmo\SoftDeleteable\SoftDeleteableListener
    tags:
        - { name: doctrine.event_subscriber, connection: default }
    calls:
        - [ setAnnotationReader, [ '@annotation_reader' ] ]
