Symfony2, relation manyToMany in a Form

Question

I start learning sf2, pretty cool, for my problem I have two tables:

Media

/**
 * @ORM\ManyToMany(targetEntity="Test\SiteBundle\Entity\Website", inversedBy="medias")
 * @ORM\JoinTable(name="media_website")

private $websites;

and Website

/**
 * @ORM\ManyToMany(targetEntity="Test\SiteBundle\Entity\Media", mappedBy="websites")

private $medias;

In my MediaType.php I have this:

$builder
        ->add('title')
        ->add('website', 'entity', array(
            'class'         =>  'TestSiteBundle:Website',
            'property'  =>  'name',
            'query_builder' => function(WebsiteRepository $er)use($user_id) {
                               return $er->getMyWebsites($user_id);
             },
            'multiple'=>false))

finally, in the twig page I have this:

<div class="form-group">
   {{ form_label(form.description, "Description", { 'label_attr': {'class': 'control-label col-md-2'} }) }}
   <div class="col-md-5">
        {{ form_widget(form.description, { 'attr': {'class': 'form-control'} }) }}
   </div>
</div>

When I try to add a Media I have this error:

Neither the property "websites" nor one of the methods "setWebsites()", "__set()" or "__call()" exist and have public access in class "Test\SiteBundle\Entity\Media".

Any help ? and many thanks to you.

I found it, for persons who have the same problem, in the relation ManyToMany you need to have multiple=>true in your FormType, so my MediaType should be:

$builder

        ->add('websites', 'entity', array(
            'class'         =>  'EveadSiteBundle:Website',
            'property'  =>  'name',
            'query_builder' => function(WebsiteRepository $er)use($user_id) {
                               return $er->getMyWebsites($user_id);
             },
            'multiple'=>true))
