Перенаправление в многошаговой форме CakeStack Overflow

Я создаю multistep form в CakePHP используя http://bakery.cakephp.org/2012/09/09/Multistep-forms.html?
Но он не перенаправляет хорошо. Как я нажимаю next на шаге 1 он перенаправляет меня на msf_index,
Вероятно, я не выполняю правильный подсчет шагов в msf_setup метод.
Почему это происходит ?
Вот код контроллера, который я только что скопировал.

class UsersController extends AppController {

/**
* use beforeRender to send session parameters to the layout view
*/
public function beforeRender() {
parent::beforeRender();
$params = $this->Session->read('form.params');
$this->set('params', $params);
}

/**
* delete session values when going back to index
* you may want to keep the session alive instead
*/
public function msf_index() {
$this->Session->delete('form');
}

/**
* this method is executed before starting the form and retrieves one important parameter:
* the form steps number
* you can hardcode it, but in this example we are getting it by counting the number of files that start with msf_step_
*/
public function msf_setup() {
App::uses('Folder', 'Utility');
$usersViewFolder = new Folder(APP.'View'.DS.'Users');
$steps = count($usersViewFolder->find('msf_step_.*\.ctp'));
$this->Session->write('form.params.steps', $steps);
$this->Session->write('form.params.maxProgress', 0);
$this->redirect(array('action' => 'msf_step', 1));
}

/**
* this is the core step handling method
* it gets passed the desired step number, performs some checks to prevent smart users skipping steps
* checks fields validation, and when succeding, it saves the array in a session, merging with previous results
* if we are at last step, data is saved
* when no form data is submitted (not a POST request) it sets this->request->data to the values stored in session
*/
public function msf_step($stepNumber) {

/**
* check if a view file for this step exists, otherwise redirect to index
*/
if (!file_exists(APP.'View'.DS.'Users'.DS.'msf_step_'.$stepNumber.'.ctp')) {
$this->redirect('/users/msf_index');
}

/**
* determines the max allowed step (the last completed + 1)
* if choosen step is not allowed (URL manually changed) the user gets redirected
* otherwise we store the current step value in the session
*/
$maxAllowed = $this->Session->read('form.params.maxProgress') + 1;
if ($stepNumber > $maxAllowed) {
$this->redirect('/users/msf_step/'.$maxAllowed);
} else {
$this->Session->write('form.params.currentStep', $stepNumber);
}

/**
* check if some data has been submitted via POST
* if not, sets the current data to the session data, to automatically populate previously saved fields
*/
if ($this->request->is('post')) {

/**
* set passed data to the model, so we can validate against it without saving
*/
$this->User->set($this->request->data);

/**
* if data validates we merge previous session data with submitted data, using CakePHP powerful Hash class (previously called Set)
*/
if ($this->User->validates()) {
$prevSessionData = $this->Session->read('form.data');
$currentSessionData = Hash::merge( (array) $prevSessionData, $this->request->data);

/**
* if this is not the last step we replace session data with the new merged array
* update the max progress value and redirect to the next step
*/
if ($stepNumber < $this->Session->read('form.params.steps')) {
$this->Session->write('form.data', $currentSessionData);
$this->Session->write('form.params.maxProgress', $stepNumber);
$this->redirect(array('action' => 'msf_step', $stepNumber+1));
} else {
/**
* otherwise, this is the final step, so we have to save the data to the database
*/
$this->User->save($currentSessionData);
$this->Session->setFlash('Account created!');
$this->redirect('/users/msf_index');
}
}
} else {
$this->request->data = $this->Session->read('form.data');
}

/**
* here we load the proper view file, depending on the stepNumber variable passed via GET
*/
$this->render('msf_step_'.$stepNumber);
}

}

Проблема может быть здесь:

 public function msf_setup() {
App::uses('Folder', 'Utility');
$usersViewFolder = new Folder(APP.'View'.DS.'Users');
$steps = count($usersViewFolder->find('msf_step_.*\.ctp'));
$this->Session->write('form.params.steps', $steps);
$this->Session->write('form.params.maxProgress', 0);
$this->redirect(array('action' => 'msf_step', 1));
}

Также я добавил четыре msf_setp файлы в view/Users лайк
msf_step_1, msf_step_2, msf_setp_3, msf_step_4,

Пожалуйста помоги. Я застрял. Спасибо заранее.
