title: Error with Form helper in CakePHP 2.0
body: <p>I'm starting out with CakePHP 2.0 and can't get past a simple login. This is my code:</p>
  
  <p><strong>AppController:</strong></p>
  
  <pre><code>class AppController extends Controller
  {
      function beforeFilter()
      {
          $this-&gt;Auth-&gt;userModel = 'User';
          $this-&gt;Auth-&gt;fields = array('username' =&gt; 'email', 'password' =&gt; 'password'); 
          $this-&gt;Auth-&gt;loginAction = array('controller' =&gt; 'users', 'action' =&gt; 'login');
          $this-&gt;Auth-&gt;loginRedirect = array('controller' =&gt; 'hotels', 'action' =&gt; 'dashboard');
      }
  }
  </code></pre>
  
  <p><strong>UsersController:</strong></p>
  
  <pre><code>class UsersController extends AppController
  {
      var $name = 'Users';
      var $helpers = array('Html','Form');
      var $components = array('Auth','Session');
  
      function beforeFilter()
      {
          $this-&gt;Auth-&gt;allow("logout");
          parent::beforeFilter();
      }
  
      function logout()
      {
          $this-&gt;redirect($this-&gt;Auth-&gt;logout());
      }
  
      function login()
      {
          if ($this-&gt;Auth-&gt;login())
          {
              $this-&gt;redirect($this-&gt;Auth-&gt;redirect());
          } else
          {
              $this-&gt;Session-&gt;setFlash(__('Invalid username or password, try again'));
          }
      }
  }
  </code></pre>
  
  <p><strong>login.ctp:</strong></p>
  
  <pre><code> echo $this-&gt;Form-&gt;create(); //'User', array('action' =&gt; 'login'));
   echo $form-&gt;Form-&gt;input('email');
   echo $form-&gt;Form-&gt;input('password');
   echo $form-&gt;Form-&gt;end('Login');
  </code></pre>
  
  <p>The error I'm getting is this:</p>
  
  <pre><code> Notice (8): Undefined variable: form [APP\View\Users\login.ctp, line 13]
   Notice (8): Trying to get property of non-object [APP\View\Users\login.ctp, line 13]
   Fatal error: Call to a member function input() on a non-object in E:\proyectos\web\swt\app\View\Users\login.ctp on line 13
  </code></pre>
  
  <p>Any ideas? Thanks in advance!</p>
