Catchable Fatal Error: Аргумент 1 передан? Symfony2.1

Я остановлен этой ошибкой:

Исправляемая фатальная ошибка: аргумент 1 передан
Joker \ CoreBundle \ Entity \ Incidentfile :: setFile () должен быть экземпляром
Symfony \ Component \ HttpFoundation \ File \ UploadedFile, заданная строка,
называется в
/Applications/MAMP/htdocs/joker-repo/vendor/symfony/symfony/src/Symfony/Component/Form/Util/PropertyPath.php
по строке 538 и определяется в
/Applications/MAMP/htdocs/joker-repo/src/Joker/CoreBundle/Entity/Incidentfile.php
линия 157

В моей сущности у меня есть сеттеры и геттеры для File. Я использовал этот метод для загрузки файла: ЭТОТ

И была проблема с разрешением для папки upload_images, но после того, как я решил, все работало нормально, но теперь что-то пошло не так.

Вот сущность

А вот и мой контроллер:

public function TestAction(Request $request){
$incfileRepo = new Incidentfile();
$formfile = $this->createForm(new IncfileType(), $incfileRepo);if ($request->isMethod('POST')) {
$formfile->bind($request);

if ($formfile->isValid()) {$em = $this->getDoctrine()->getManager();

$em->persist($incfileRepo);
$em->flush();

return $this->redirect($this->generateUrl('incident_show'));
}
}

$spotEntity = $this->getCurrentSpot();
$sentryEntity = $this->getCurrentSentry();
$messagesCollection = $this->getDoctrine()->getRepository('JokerCoreBundle:Message')->findBy(array(
'spot'  =>  $spotEntity,
'sentry'    =>  $sentryEntity
), array(
'sent_date' =>  'DESC'
));

return $this->render('JokerAdminBundle:incidents:addfullform.html.twig', $this->getViewConstants(array(
'formfile'=>$formfile->createView(),
'spot'  =>  $spotEntity,
'sentry'    =>  $sentryEntity,
'messagesCollection'    =>  $messagesCollection,
)));}

Форма в веточке:

 <form action="" method="post">
{{ form_rest(formfile) }}

<div class="singleTableForm">
<input style="float: left; margin-left: 338px; " type="submit" name="" class="button" value="Add" />
</div>
</form>
