Ok binding issue solved (enctype syntax error) : i'll give you the code i use. maybe it will help...

I have a Gallery Entity

class Gallery
{
    protected $id;
    protected $name;
    protected $description;
    private $urlName;
    public $files; // the array which will contain the array of Uploadedfiles

    // GETTERS & SETTERS ...

    public function getFiles() {
        return $this->files;
    }
    public function setFiles(array $files) {
        $this->files = $files;
    }

    public function __construct() {
        $files = array();
    }
}

I have a form class that generate the form

class Create extends AbstractType {

    public function buildForm(FormBuilder $builder, array $options) {

        $builder->add('name','text',array(
            "label" => "Name",
            "required" => TRUE,
        ));
        $builder->add('description','textarea',array(
            "label" => "Description",
            "required" => FALSE,
        ));
        $builder->add('files','file',array(
            "label" => "Fichiers",
            "required" => FALSE,
            "attr" => array(
                "accept" => "image/*",
                "multiple" => "multiple",
            )
        ));
    }
}

Now in the controller

class GalleryController extends Controller
{
    public function createAction() {
        $gallery = new Gallery();
        $form = $this->createForm(new Create(), $gallery);
        // Altering the input field name attribute
        $formView = $form->createView();
        $formView->getChild('files')->set('full_name', 'create[files][]');

        $request = $this->getRequest();
        if($request->getMethod() == "POST")
        {
            $form->bindRequest($request);

            // print "
".print_r($gallery->getFiles(),1)."
";
            if($form->isValid())
            {
                // Do what you want with your files
                $this->get('gallery_manager')->save($gallery);
                return $this->redirect($this->generateUrl("_gallery_overview"));
            }
        }

        return $this->render("GalleryBundle:Admin:create.html.twig", array("form" => $formView));
    }
}

Hope this help...

NB: If someone know a better way to alter this f** name attribute, maybe in the FormView class or by declaring a new field type, feel free to show us your method...
