How to Redirect out of an Event? - symfony

Question

I am listening to security.authentication.success event. Everytime a customer logs in i need to check if he still got main information. If not, then i want to redirect him to the form for creation. It is running good but in which way can i redirect out of an event? Simply returning an Redirect Object does not work.
Service:
applypie_userbundle.newuser_listener:
class: Applypie\Bundle\UserBundle\EventListener\NewUserListener
arguments: [#router]
tags:
- { name: kernel.event_listener, event: security.authentication.success, method: onLogin }
Listener:
namespace Applypie\Bundle\UserBundle\EventListener;
use Symfony\Component\Security\Core\Event\AuthenticationEvent;
use Symfony\Component\Security\Core\SecurityContext;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\Routing\Router;
class NewUserListener
{
protected $context;
protected $router;
public function __construct(Router $router)
{
$this->router = $router;
}
/**
* #param AuthenticationEvent $event
*
* if current user neither have an applicant row or an company row, redirect him to create applicant row
*/
public function onLogin(AuthenticationEvent $event)
{
$user = $event->getAuthenticationToken()->getUser();
if(!$user->getApplicant() && !count($user->getCompanies()))
{
return new RedirectResponse($this->router->generate('applypie_user_applicant_create'));
}
}
}

To cut the long story short, yes, you are listening to the correct event but... is someone waiting your method return?... NOPE!
I can't test this right now, but this is the idea:
security.yml
firewalls:
main:
pattern: ^/
form_login:
success_handler: my.security.login_handler
services.yml
services:
my.security.login_handler:
class: Applypie\Bundle\UserBundle\EventListener\NewUserListener
arguments: [#router]
NewUserListener
namespace Applypie\Bundle\UserBundle\EventListener;
use Symfony\Component\Security\Http\Authentication\AuthenticationSuccessHandlerInterface;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\Routing\RouterInterface;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\HttpFoundation\Request;
class NewUserListener implements AuthenticationSuccessHandlerInterface
{
protected $router;
public function __construct(RouterInterface $router)
{
$this->router = $router;
}
protected function getResponse($name)
{
$url = $this->router->generate($name);
$response = new RedirectResponse($url);
return $response;
}
public function onAuthenticationSuccess(Request $request, TokenInterface $token)
{
$user = $token->getUser();
$route = 'user_home';
if(!$user->getApplicant() && empty($user->getCompanies())) {
$route = 'applypie_user_applicant_create';
}
return $this->getResponse($route);
}
}

Do something just after symfony2 login success and before redirect?
