Parameter undefined in FOSUserBundle

Question

I'm adding new features in a Symfony2 Web Application, and after few development the edit user feature stop working.

For some reason the erro is showed in edit user screen, not in show user.

The error:

The parameter "fos_user.template.theme" must be defined.
500 Internal Server Error - InvalidArgumentException

The editAction method:

/**
 * Edit the user
 */
public function editAction()
{
    $user = $this->container->get('security.context')->getToken()->getUser();
    if (!is_object($user) || !$user instanceof UserInterface) {
        throw new AccessDeniedException('This user does not have access to this section.');
    }

    $form = $this->container->get('fos_user.profile.form');
    $formHandler = $this->container->get('fos_user.profile.form.handler');

    $process = $formHandler->process($user);
    if ($process) {
        $this->setFlash('notice', 'As alterações foram feitas com sucesso.');

        return new RedirectResponse($this->container->get('router')->generate('fos_user_profile_show'));
    }

    return $this->container->get('templating')->renderResponse(
        'FOSUserBundle:Profile:edit.html.'.$this->container->getParameter('fos_user.template.engine'),
        array('form' => $form->createView(), 'theme' => $this->container->getParameter('fos_user.template.theme'))
    );
}

I believe something is missing on config.yml, but I can't add the correct paramter on fos_user.template.theme:

fos_user:
    db_driver: orm # other valid values are 'mongodb', 'couchdb' and 'propel'
    firewall_name: main
    user_class: App\UserBundle\Entity\User
    registration:
        form:
            type: duo_vozi_user_registration
    profile:
        form:
            type: duo_vozi_user_profile
    from_email:
        address:        vozi@vozi.com.br
        sender_name:    VOZI

These are the version of used components:

    "php": ">=5.3.3",

    "doctrine/orm": ">=2.2.3,<2.4-dev",

Answer 1

After some research to find the origin of your controller's code, it seems that it comes from an old version of FOSUserBundle (1) (2) (3). So I suggest you to upgrade your Symfony2 or use the last version of FOSUserBundle and use the last version of the documentation.

Answer 2

If you use twig as your template engine, remove all calls to $this->container->getParameter('fos_user.template.theme') in your code and replace them with the static string 'twig'.

This is true since FOSUserBundle removed the option to switch to a different templating engine.

@Victor, the editAction() method would become :

/**
 * Edit the user
 */
public function editAction()
{
    $user = $this->container->get('security.context')->getToken()->getUser();
    if (!is_object($user) || !$user instanceof UserInterface) {
        throw new AccessDeniedException('This user does not have access to this section.');
    }

    $form = $this->container->get('fos_user.profile.form');
    $formHandler = $this->container->get('fos_user.profile.form.handler');

    $process = $formHandler->process($user);
    if ($process) {
        $this->setFlash('notice', 'As alterações foram feitas com sucesso.');

        return new RedirectResponse($this->container->get('router')->generate('fos_user_profile_show'));
    }

    return $this->container->get('templating')->renderResponse(
        'FOSUserBundle:Profile:edit.html.twig',
        array('form' => $form->createView(), 'theme' => $this->container->getParameter('fos_user.template.theme'))
    );
}
