_forward() in Zend does not work?

[lop1th3]

Here is a code:\[code\] public function loginAction(){ $form = new Application_Form_Login(); $this->view->form = $form; if($this->_request->isPost()) { self::$dataForm = $this->_request->getPost(); if($this->form->isValid(self::$dataForm)) { return $this->_forward('authorization'); } else { $this->form->populate(self::$form); } }}public function authorizationAction(){ if($this->_request->isPost()) { $auth = Zend_Auth::getInstance(); $authAdapter = new Application_Model_User($this->user->getAdapter(),'user'); $authAdapter->setIdentityColumn('USERNAME') ->setCredentialColumn('PASSWORD'); $password = md5(self::$dataForm['password']); $authAdapter->setIdentity(self::$dataForm['username']); $authAdapter->setCredental($password); $result = $auth->authenticate($authAdapter); echo 'ok'; /* if($result->isValid()) { //$this->_forward('authorized', 'user'); echo 'ok'; }*/ }}\[/code\]Any idea why it does not work? I didn't get any error just blank page.
