exception `Unable to find entity` after the addition of FOSUserBundle

问题

I follow steps from my book (based on symfony 2.0.10, I'm using Symfony2.6.1 with FOSUB 2.0).

I build project with CRUD that display data from db just fine (Mountain controller inside My/BackendBundle).

Then I want display project only for logged user admin (with ROLE_SUPER_ADMIN, that exist in my for_user table inside db with CRUD data).

But when openning ../web/ its result exception Unable to find Mountain entity. from Mountain controller showAction($id)

#\src\My\BackendBundle\Controller\MountainController.php
/**
 * Finds and displays a Mountain entity.
 *
 * @Route("/{id}", name="mountain_show")
 * @Method("GET")
 * @Template()
 */
public function showAction($id)
{
    $em = $this->getDoctrine()->getManager();

    $entity = $em->getRepository('MyBackendBundle:Mountain')->find($id);

    if (!$entity) {
        throw $this->createNotFoundException('Unable to find Mountain entity.');
    }

    $deleteForm = $this->createDeleteForm($id);

    return array(
        'entity'      => $entity,
        'delete_form' => $deleteForm->createView(),
    );

Add requirements parameter to your route description and also you can skip entity fetching by leaving it for Symfony to serve you:

#\src\My\BackendBundle\Controller\MountainController.php
/**
 * Finds and displays a Mountain entity.
 *
 * @Route("/{mountain}", name="mountain_show", requirements={"mountain": "\d+"})
 * @Method("GET")
 * @Template()
 */
public function showAction(Mountain $mountain)
{
    $deleteForm = $this->createDeleteForm(mountain->getId());

    return array(
        'entity'      => $mountain,
        'delete_form' => $deleteForm->createView(),
    );
}

Also, @Template() considered as bad practice and it is a better idea to return a Response object:

#\src\My\BackendBundle\Controller\MountainController.php
/**
 * Finds and displays a Mountain entity.
 *
 * @Route("/{mountain}", name="mountain_show", requirements={"mountain": "\d+"})
 * @Method("GET")
 */
public function showAction(Mountain $mountain)
{
    $deleteForm = $this->createDeleteForm(mountain->getId());

    return $this->render(
        'MyBackendBundle:Mountain:show',
        array(
            'entity'      => $mountain,
            'delete_form' => $deleteForm->createView(),
        )
    );
}

----edit---

@Aistis with this code

 /**
 * @Route("/{id}", name="mountain_show", requirements={"id": "\d+"}))
 * @Template()
 */
public function showAction($id)
{
    $em = $this->getDoctrine()->getManager();
    var_dump($id);
    $entity = $em->getRepository('MyBackendBundle:Mountain')->find($id);

    if (!$entity) {
        throw $this->createNotFoundException('Unable to find Mountain entity.');
    }

    $deleteForm = $this->createDeleteForm($id);

    return array(
        'entity'      => $entity,
        'delete_form' => $deleteForm->createView(),
    );
}

it's works. But why he gets /login as a parameter?
