I have a problem with my form,i have this error every time i want to save a comment :

Expected argument of type array or Traversable and ArrayAccess, object given

firstly i create my class commentType :

    public function buildForm(FormBuilder $builder, array $options)
{
    $builder
        ->add('comment', 'textarea')
        ->add('commentedName', 'text')
        ->add('idNews','hidden',  array('error_bubbling'=>true))
        ->add('country', 'text')
        ->add('email','email')
        ->add('captcha', 'captcha');
}

I customise my form :

   public function getDefaultOptions(array $options){

$collectionConstraint = new Collection (array (
    'email' => new Email(array('message' => 'invalid address email')),
    'commentedName' => array(new MaxLength(array('limit' => 30, 'message' => ''))),
    'comment' => array(new MinLength(array('limit' => 20, 'message' => ''))),
    'country' => new MinLength(array('limit' => 3, 'message' => '')),
    'idNews' => array(new MaxLength(array('limit' => 30, 'message' => ''))),
));

return array('validation_constraint' => $collectionConstraint);
}

then in my controller i call my form and i save data in DB :

$comment =  new \Mybundle\BackendBundle\Entity\Comments();

$form = $this->createForm(new \Mybundle\MainBundle\Form\CommentType(), $comment);

    $request = $this->get('request');
if ($request->getMethod() == 'POST') {
    $form->bindRequest($request);

    if ($form->isValid()) {
        $idNews= $this->getDoctrine()
            ->getRepository('Mybundle\BackendBundle\Entity\News')
            ->find($id);

        $comment->setIdNews($idNews);

        $em = $this->getDoctrine()->getEntityManager();
        $em->persist($comment);
        $em->flush();

       return $this->redirect($this->generateUrl('News',array('id' => $id,'slug'=>$slug)));

and in my twig i do :

<table style="float: right;" >
<tbody>
    <tr>
        <td>{{ form_widget(form.commentedName) }} </td>
        <td>{{ form_label(form.commentedName, "name") }}</td>
    </tr>
    <tr>
        <td class="comment-error">{{ form_errors(form.commentedName) }}</TD>
    </tr>
    <tr>
        <td>{{ form_widget(form.country) }} </td>
        <td>{{ form_label(form.country, "country") }}</td>
    </tr>
    <tr>
        <td class="comment-error">{{ form_errors(form.country) }}</TD>
    </tr>
    <tr>
        <td class="large_text">{{ form_widget(form.email) }} </td>
        <td>{{ form_label(form.email, "address") }}</td>
    </tr>
    <tr>
        <td class="comment-error">{{ form_errors(form.email) }}</td>
    </tr>
    <tr>
        <td>{{ form_widget(form.comment) }} </td>
        <td>{{ form_label(form.comment, "comment") }}</td>
    </tr>
    <tr>
        <td class="comment-error">{{ form_errors(form.comment) }}</td>
    </tr>
    <tr>
        <td>{{ form_widget(form.captcha) }} </td>
    </tr>

 <tr>
        <td class="comment-error">{{ form_errors(form) }}</td>
    </tr>  

I remark when i change in my cotroller the object "$comment" with "null" in the line above i didn't have the error but i can"t save data in database...

Anyone have an idea?

With a collection constraint you can only validate arrays (or anything that implements Traversable). You have to move to annotation in your Comments class.
