Render controller in TWIG and show form errors

I have indexAction and contactAction

contactAction is a simple form with no mapped fields (FormType) like below:

* @Route("/contact", name="contact")
* @Template()
* @param Request $request
* @return array
public function contactAction(Request $request)
$form = $this->createForm(new ContactType());


if ($form->isValid()) {
$firstName = $form->get('first_name')->getData();
$lastName = $form->get('last_name')->getData();
$email = $form->get('email')->getData();
$message = $form->get('message')->getData();
return array(
'form' => $form->createView()

and i render this form in my indexAction with this TWIG command:

{{ render(controller('RusselBundle:Default:contact')) }}

Everything is okey, if page is not reloaded, HTML5 validators works fine, but if form have some errors like: firstName length, error's not show at all, how can i do, so that errors showed up in the form indexAction? Any help would be appreciated. I'm just curious it's possible, and if - how ? Sorry for my english....

Rather than using the request passed into the action you should get the master request from the request stack. As @DebreczeniAndrĂ¡s says, when you use the render(controller()) you are using a newly created sub-request rather than the request that was actually passed to the page on load (the master request).

public function contactAction(Request $request)
    $request = $this->get('request_stack')->getMasterRequest();

    $form = $this->createForm(new ContactType());
