Symfony2.7 form not valid - symfony

Question

I'm developping a blog using Symfony 2.7. I've an ArticleBundle and a CommentBundle. My entities Article and Comment are linked by a ManyToOne relation.
When I try to send a comment, it fails. The $form->isValid() method returns false.
Here, my add method to send a comment :
public function addAction(Article $article, Request $request){
$comment = new Comment();
$form = $this->createForm(new CommentType(), $comment);
$form->handleRequest($request);
if($form->isValid()){
$comment->setArticle($article);
$em = $this->getDoctrine()->getManager();
$em->persist($comment);
$em->flush();
return $this->redirect($this->generateUrl('esgi_article_view', array(
'id' => $article->getId()
)));
} else{
return $this->render('ESGICommentBundle:Comment:add.html.twig', array(
'form' => $form->createView(),
'article' => $article
));
}
}
My comment form is inclued into article's view like this :
{{ render(controller("ESGICommentBundle:Comment:add", { 'id' : article.id })) }}
And here my form :
{{ form_start(form) }}
<div class="form-group">
<div class="row">
<div class="col-xs-12 col-sm-6 col-md-8">
{{ form_label(form.author, "Auteur") }}
{{ form_widget(form.author, { 'attr' : { 'class' : 'form-control' } }) }}
{{ form_errors(form.author) }}
</div>
</div>
<div class="row">
<div class="col-xs-12 col-sm-6 col-md-8">
{{ form_label(form.email, "Email (optionnel)") }}
{{ form_widget(form.email, { 'attr' : { 'class' : 'form-control' } }) }}
{{ form_errors(form.email) }}
</div>
</div>
<div class="row">
<div class="col-xs-12 col-sm-6 col-md-8">
{{ form_label(form.content, "Commentaire") }}
{{ form_widget(form.content, { 'attr' : { 'class' : 'form-control' } }) }}
{{ form_errors(form.content) }}
</div>
</div>
</div>
<button class="btn btn-success" type="submit">Poster</button>
{{ form_end(form) }}
Thanks, have a nice day !

IF you submit the form, you should have all the errors in the profiler bar(there is a form icon which you can click to see errors in the submitted form)
