Symfony 2.8 FosUserBundle User Locale Internacionalization doesn`t work - php

Question

I create my app with Symfony 2.8 and FosUserBundle. I wiew a lot of tutorials and I don´t understand why it does not take the value of the user session.
I do it like the example in the web of symfony: https://symfony.com/doc/2.8/session/locale_sticky_session.html
The configuration of the first Event Listener is correct but the second event Listener doesn't set the local value in session
<?php
//AppBundle/Controller/DefaultController.php
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
class DefaultController extends Controller
{
/**
* #Route("/", name="homepage")
*/
public function indexAction(Request $request)
{
// replace this example code with whatever you need
$locale = $request->getLocale();
$user = $event->getAuthenticationToken()->getUser();
var_dump($locale);
return $this->render('default/index.html.twig', array(
'base_dir' => realpath($this->container->getParameter('kernel.root_dir') . '/..'),
));
/*return $this->render('default/index.html.twig', array(
'base_dir' => realpath($this->container->getParameter('kernel.root_dir').'/..').DIRECTORY_SEPARATOR,
));*/
}
}
Event Listeners:
<?php
// src/AppBundle/EventListener/LocaleListener.php
namespace AppBundle\EventListener;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
class LocaleListener implements EventSubscriberInterface
{
private $defaultLocale;
public function __construct($defaultLocale = 'en')
{
$this->defaultLocale = $defaultLocale;
}
public function onKernelRequest(GetResponseEvent $event)
{
$request = $event->getRequest();
if (!$request->hasPreviousSession()) {
return;
}
// try to see if the locale has been set as a _locale routing parameter
if ($locale = $request->attributes->get('_locale')) {
$request->getSession()->set('_locale', $locale);
} else {
// if no explicit locale has been set on this request, use one from the session
$request->setLocale($request->getSession()->get('_locale', $this->defaultLocale));
}
}
public static function getSubscribedEvents()
{
return array(
// must be registered after the default Locale listener
KernelEvents::REQUEST => array(array('onKernelRequest', 15)),
);
}
}
UserLocaleListener.php
<?php
// src/AppBundle/EventListener/UserLocaleListener.php
namespace AppBundle\EventListener;
use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\Security\Http\Event\InteractiveLoginEvent;
/**
* Stores the locale of the user in the session after the
* login. This can be used by the LocaleListener afterwards.
*/
class UserLocaleListener
{
/**
* #var Session
*/
private $session;
public function __construct(Session $session)
{
$this->session = $session;
}
/**
* #param InteractiveLoginEvent $event
*/
public function onInteractiveLogin(InteractiveLoginEvent $event)
{
$user = $event->getAuthenticationToken()->getUser();
if (null !== $user->getLocale()) {
$this->session->set('_locale', $user->getLocale());
}
}
}
The configuration of config.yml is:
parameters:
locale: en
fos_user:
db_driver: orm
firewall_name: main
user_class: AppBundle\Entity\User
from_email:
address: "%mailer_user%"
sender_name: "%mailer_user%"
registration:
confirmation:
enabled: true
resetting:
email:
from_email:
address: manuelterronalvarez#gmail.com
sender_name: App Resetting
jms_i18n_routing:
default_locale: "%locale%"
locales: [es, en]
strategy: prefix_except_default
Any ideas? Thanks in advance
