title: Method SessionHelper::write does not exist Error
body: <p>I am trying to use sessions in my CakePHP 2.3 application.  When I add this to my View:</p>
  
  <pre><code>           $this-&gt;Session-&gt;write('key','value');
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>Warning (512): Method SessionHelper::write does not exist [CORE\Cake\View\Helper.php, line 179]
  </code></pre>
  
  <p>I have tried adding this to my controller:</p>
  
  <pre><code>var $helpers = array('Html', 'Form', 'Js'=&gt;array("Jquery"),"Session");
  public $components = array('RequestHandler','Session');
  </code></pre>
  
  <p>But the error still occurs.  Anyone know what is going on?</p>
  
  <p>thanks</p>
