Codeigniter, Facebook SDK javascript, PHP SDK de Redirection après facebook login n'est pas getUser() jusqu'à ce que l'actualisation

Le processus est comme suit.

1. User clicks Facebook Login button
2. User signs in and grants perms
3. Facebook redirects uses FB.Event.subscribe auth.login to redirect my login controller
4. My login controller loads the fbconnect module and chains the method Connect()
5. Connect() Checks if there is a facebook user using getUser() and if true checks if they are an existing user to log them in or returns false if no facebook user was found.

Tout fonctionne sauf le seul problème, c'est après être redirigé vers la page de connexion vous Connecter retourne False lorsqu'il devrait en fait être vrai sine le fbuser est connecté et a accordé des permissions. Si j'actualise cependant, tout fonctionne, l'utilisateur est connecté, s'il existe, ou si de nouvelles est envoyé à la page d'inscription. Ci-dessous mon code..

      <div id="fb-root"></div>
    <script>
      //initializing API
      window.fbAsyncInit = function() {
        FB.init({appId: '(My app id)', status: true, cookie: true,
                 xfbml: true, //channel.html file
                 oauth  : true
                 });
                 FB.Event.subscribe('auth.login', function(response) {
                 window.location='http://www.(Mysite).com/login';
                 });
                 FB.Event.subscribe('auth.logout', function(response) {
                 window.location='http://www.(Mysite).com/logout';
                 });
                 };
      (function() {
        var e = document.createElement('script'); e.async = true;
        e.src = document.location.protocol +
          '//connect.facebook.net/en_US/all.js';
        document.getElementById('fb-root').appendChild(e);
      }());
    </script>

Fbconnect.php

class Fbconnect extends MX_Controller {
public $fb_user = null;
public $fb_user_id = null;
//Initilize Fabebook
public function __construct() 
{   
parent::__construct();
$this->config->load("facebook");
require 'facebook.php';
$this->facebook = new Facebook(array(
'appId' => $this->config->item('appId'),
'secret' => $this->config->item('Secret')
));
//Get user from FB
$this->fb_user_id = $this->facebook->getUser();
if ($this->fb_user_id):
try {
//Proceed knowing you have a logged in user who's authenticated.
$this->fb_user = (object)$this->facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$this->fb_user = null;
}
endif;
}
public function connect(){
//Check for FB object
if($this->fb_user):
//FB Object found
//Check if user exists
$this->load->model('facebook/m_facebook');
$user = $this->m_facebook->getUser($this->fb_user->id);
//If we find a user and fb connect is true
if($user):
//user found log them in
if($this->ion_auth->login($user->username, $user->password, true, true)):
redirect('', 'refresh');
endif;
else:
//There is a fb object & the user is not logged in & doesnt exist in db yet must be new 
redirect('signup/facebook', 'refresh');
endif;
else: 
//No FB user or user not logged in                                  
return false;
endif;    
}

La auth/code de connexion (juste la partie qui consiste à facebook)

 $this->load->module('facebook/fbconnect')->connect();
