FOSUserBundle - Registration controller override error - symfony

Question

I am trying to override the registration controller of FOSUserBundle.
Here's my configuration :
services:
project.registration.controller:
class: Project\UserBundle\Controller\RegistrationController
arguments: [ #event_dispatcher,#fos_user.registration.form.factory,#fos_user.user_manager,#security.token_storage]
And the controller so far:
<?php
namespace Project\UserBundle\Controller;
use Symfony\Component\DependencyInjection\ContainerInterface;
use Symfony\Component\HttpFoundation\RedirectResponse;
use FOS\UserBundle\Form\Factory\FactoryInterface;
use FOS\UserBundle\Model\UserManagerInterface;
use Symfony\Component\EventDispatcher\EventDispatcherInterface;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
use FOS\UserBundle\Controller\RegistrationController as BaseController;
class RegistrationController extends BaseController
{
public function __construct(EventDispatcherInterface $eventDispatcher, FactoryInterface $formFactory, UserManagerInterface $userManager, TokenStorageInterface $tokenStorage)
{
parent::__construct($eventDispatcher, $formFactory, $userManager, $tokenStorage);
}
However everytime i try to go to the registration page I meet this error :
Catchable Fatal Error: Argument 1 passed to Project\UserBundle\Controller\RegistrationController::__construct() must implement interface Symfony\Component\EventDispatcher\EventDispatcherInterface, none given, called in C:\wamp\www\cmagic\vendor\symfony\symfony\src\Symfony\Component\HttpKernel\Controller\ControllerResolver.php on line 187 and defined
I think I followed for controllers used as services or did I miss a step ?
EDIT : This is for symfony 2.8

It worked for me in Symfony 3, but getParent(){} for bundles is already deprecated in 3.4 version and disabled in 4.
namespace AppBundle;
use Symfony\Component\HttpKernel\Bundle\Bundle;
class AppBundle extends Bundle
{
public function getParent()
{
return 'FOSUserBundle';
}
}
namespace AppBundle\Controller;
use FOS\UserBundle\Controller\RegistrationController as BaseController;
use FOS\UserBundle\Event\FormEvent;
use FOS\UserBundle\FOSUserEvents;
use Symfony\Component\EventDispatcher\EventDispatcherInterface;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
class RegistrationController extends BaseController
{
/**
* #param Request $request
*
* #return Response
*/
public function registerAction(Request $request)
{
/** #var $formFactory FactoryInterface */
$formFactory = $this->get('fos_user.registration.form.factory');
/** #var $userManager UserManagerInterface */
$userManager = $this->get('fos_user.user_manager');
/** #var $dispatcher EventDispatcherInterface */
$dispatcher = $this->get('event_dispatcher');
$user = $userManager->createUser();
$user->setEnabled(true);
$event = new GetResponseUserEvent($user, $request);
$dispatcher->dispatch(FOSUserEvents::REGISTRATION_INITIALIZE, $event);
if (null !== $event->getResponse()) {
return $event->getResponse();
}
$form = $formFactory->createForm();
$form->setData($user);
$form->handleRequest($request);
if ($form->isSubmitted()) {
if ($form->isValid()) {
$event = new FormEvent($form, $request);
$dispatcher->dispatch(FOSUserEvents::REGISTRATION_SUCCESS, $event);
$userManager->updateUser($user);
if (null === $response = $event->getResponse()) {
$url = $this->generateUrl('fos_user_registration_confirmed');
$response = new RedirectResponse($url);
}
$dispatcher->dispatch(FOSUserEvents::REGISTRATION_COMPLETED, new FilterUserResponseEvent($user, $request, $response));
return $response;
}
$event = new FormEvent($form, $request);
$dispatcher->dispatch(FOSUserEvents::REGISTRATION_FAILURE, $event);
if (null !== $response = $event->getResponse()) {
return $response;
}
}
return $this->render('#FOSUser/Registration/register.html.twig', array(
'form' => $form->createView(),
));
}
}
