You only need set the data of your field:

    
    class EventController extends Controller
    {
        // ...

        public function addAction()
        {
           $request = $this->getRequest();
            $em = $this->getDoctrine()->getManager();

            $event = new Event();
            $form = $this->createForm(new EventType(), $event);

            // -------------------------------------------
            // Suppose you have a place entity..
            $form->get('place')->setData($place);
            // That's all..
            // -------------------------------------------

            $formHandler = new EventHandler($form, $request, $em);

            if($formHandler->process()) {
                $this->get('session')->getFlashBag()->add('success', "L'évènement a bien été ajouté.");
                return $this->redirect($this->generateUrl('photo_event_list'));
            }

            return $this->render('RoyalMovePhotoBundle:Event:add.html.twig', array(
                'form' => $form->createView()
            ));
        }
    }
