Extending Controller - Nothing Happens - symfony

Question

I'm trying to figure that problem for a long day.
I have Sonata User Bundle installed and I use it to manage users and profile edition and so on.
BUT, I a need to override Sonata Profile Controller.
If I understood correctly (I'm a perfect beginner in Symfony), I have to extend SonataUserBundle (which has been done using the easy extend bundle).
So, when I declare a new controller, nothing happens. Not even an error message.
Any ideas ?
Here are my files
[ BUNDLE EXTENSION FILE ]
// ApplicationSonataUserBundle.php
namespace Application\Sonata\UserBundle;
use Symfony\Component\HttpKernel\Bundle\Bundle;
class ApplicationSonataUserBundle extends Bundle
{
/**
* {#inheritdoc}
*/
public function getParent()
{
return 'SonataUserBundle';
}
}
[ CONTROLLER FILE ]
namespace Application\Sonata\UserBundle\Controller;
use Sonata\UserBundle\Controller\ProfileFOSUser1Controller as BaseController;
class ProfileFOSUser1Controller extends BaseController {
public function editProfileAction() {
die('toto');
$user = $this->getUser();
if (!is_object($user) || !$user instanceof UserInterface) {
throw new AccessDeniedException('This user does not have access to this section.');
}
$form = $this->get('sonata.user.profile.form');
$formHandler = $this->get('sonata.user.profile.form.handler');
$process = $formHandler->process($user);
if ($process) {
$this->setFlash('sonata_user_success', 'profile.flash.updated');
return $this->redirect($this->generateUrl('sonata_user_profile_edit'));
}
return $this->render('SonataUserBundle:Profile:edit_profile.html.twig', array(
'form' => $form->createView(),
'breadcrumb_context' => 'user_profile',
));
}
}

Answer 1

You have die('toto'); as first line in the controller method, isn't that going to terminate all code below?

Ok so I have found the answer by myself :)
I forgot to specify the classes I needed
use FOS\UserBundle\Model\UserInterface;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Security\Core\Exception\AccessDeniedException;
use Sonata\UserBundle\Controller\ProfileFOSUser1Controller as BaseController;
I cleared the cache and everything was ok !
Thanks all !
