 If you wish to create it from within a controller or any other service that has
 access to the form factory, you then use::

    class FriendMessageController extends Controller
    use Symfony\Component\DependencyInjection\ContainerAware;

    class FriendMessageController extends ContainerAware
    {
        public function newAction(Request $request)
        {
            $form = $this->createForm('acme_friend_message');
            $form = $this->get('form.factory')->create('acme_friend_message');

            // ...
        }
    }

 If you extend the ``Symfony\Bundle\FrameworkBundle\Controller\Controller`` class, you can simply call::

    $form = $this->createForm('acme_friend_message');

 You can also easily embed the form type into another form::

    // inside some other "form type" class
