An exception has been thrown during the rendering of a template ("").

Bonjour,

J'essaye d'afficher un block Sonata mais j'ai l'erreur:

Code:

An exception has been thrown during the rendering of a template ("").

N'ayant pas plus d'informations, je ne sais pas du tout où peut se trouver l'erreur.
Mon code pour le Controller:

Code:

12
13
public function showAction(UserProfileMenu $block)
    {
        $user = $this->getUser();
 
        if (!is_object($user) || (!$user instanceof FOSUserInterface && !$user instanceof LDapUserInterface)) {
            throw $this->createAccessDeniedException('This user does not have access to this section.');
        }
 
        return $this->render('bundles/ApplicationSonataUserBundle/Profile/show.html.twig', array(
            'user' => $user,
            'blocks' => $block,
        ));
    }

show.html.twig:

Code:

1

    <div class="span6 col-lg-12">
            <h2>Bonjour <b>{{ app.user.firstname }}</b></h2>
            <p>Vous êtes connecté avec le nom d'utilisateur <em>{{ app.user.username }}</em>.</p>
        </div>
 
        {{ sonata_block_render(blocks) }}

Et enfin, le code de mon block si cela peut servir:

Quelqu'un a déjà eu cette erreur? Ou a des pistes? Je suis bloquée :/
Merci d'avance
