[SF2][SF] Menu - Drzewo kategorii w oparciu o tree nested Opcje

[swiezak]

Witam.
Mam problem z uzyskaniem menu w formie drzewa. Korzystam z Tree nested i otrzymuję kod błędu: "Error: Call to a member function childrenHierarchy() on a non-object".
Dopiero zaczynam przygode z SF2, dlatego prosze o wyrozumialosc.

W kontrolerze mam taki zapis:

    public function menucategoriesAction()
    {
		$em = $this->getDoctrine()->getEntityManager();
		$repo = $em->getRepository('MlFrontendBundle:Categories')->findAll();
		if (!$repo) {
			throw $this->createNotFoundException('Kategorie - brak rekordów!');
		 }
 
 		$options = array(
                       'decorate' => true,
 			'rootOpen' => '<ul>',
 			'rootClose' => '</ul>',
 			'childOpen' => '<li>',
 			'childClose' => '</li>',
			'nodeDecorator' => function($node) {
 				return '<a href="/category/'.$node['slug'].'">'.$node[$field].'</a>';
 			}
 		);
		$htmlTree = $repo->childrenHierarchy(
			null, /* starting from root nodes */
			false, /* true: load all children, false: only direct */
			$options
		);
 
		return $this->render('MlFrontendBundle:Default:menucategories.html.twig', array('htmlTree' => $htmlTree));
}
