Unbekannter Entitäts-Namespace-Alias ​​in symfony2

Hey, ich habe zwei Bündel in meinem symfony2-Projekt. Eines ist Bundle und das andere ist PatentBundle. 

Meine app/config/route.yml-Datei ist 

MunichInnovationGroupPatentBundle:
resource: "@MunichInnovationGroupPatentBundle/Controller/"
type:     annotation
prefix:   /
defaults:  { _controller: "MunichInnovationGroupPatentBundle:Default:index" }

MunichInnovationGroupBundle:
resource: "@MunichInnovationGroupBundle/Controller/"
type:     annotation
prefix:   /v1
defaults:  { _controller: "MunichInnovationGroupBundle:Patent:index" }

login_check:
pattern:   /login_check

logout:
pattern:   /logout

in meinem Controller habe ich 

<?php
namespace MunichInnovationGroup\PatentBundle\Controller;

use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
use JMS\SecurityExtraPatentBundle\Annotation\Secure;
use Symfony\Component\Security\Core\Exception\AccessDeniedException;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use Symfony\Component\Security\Core\SecurityContext;

use MunichInnovationGroup\PatentBundle\Entity\Log;
use MunichInnovationGroup\PatentBundle\Entity\UserPatent;
use MunichInnovationGroup\PatentBundle\Entity\PmPortfolios;
use MunichInnovationGroup\PatentBundle\Entity\UmUsers;
use MunichInnovationGroup\PatentBundle\Entity\PmPatentgroups;
use MunichInnovationGroup\PatentBundle\Form\PortfolioType;
use MunichInnovationGroup\PatentBundle\Util\SecurityHelper;
use Exception;
/**

class PortfolioController extends Controller {
/**

   public function indexAction(Request $request) {
    $portfolios = $this->getDoctrine()
    ->getRepository('MunichInnovationGroupPatentBundle:PmPortfolios')
    ->findBy(array('user' => '$user_id'));

           // rest of the method
  }

Mein Hauptpaket: MunichInnovationGroupPatentBundle.php

 <?php

  namespace MunichInnovationGroup\PatentBundle;

  use Symfony\Component\HttpKernel\Bundle\Bundle;

  class MunichInnovationGroupPatentBundle extends Bundle
 {
 }

wenn ich versuche, localhost/web/app_dev.php/portfolio zu laden

Es sagt

   Unknown Entity namespace alias 'MunichInnovationGroupPatentBundle'.

Ich kann diesen Fehler nicht herausfinden. Bitte helfen Sie mir, wenn jemand eine Ahnung hat, dass ich viel gegoogelt habe :(

Danke im Voraus 500 Interner Serverfehler - ORMException
