title: Action Helper by name EntityManger not found
body: <p>Just started building an app with the zend framework. I've working on a zend server 5.5. When I try to open the first controller I created, I get the following error message:</p>
  
  <pre><code>Application Error
  Message: Action Helper by name EntityManager not found
  
  Stack trace:
  #0 c:\Program Files (x86)\Zend\ZendServer\share\ZendFramework\library\Zend\Controller\Action\HelperBroker.php(293): Zend_Controller_Action_HelperBroker::_loadHelper('EntityManager')
  ...
  </code></pre>
  
  <p>My guess is that I'm missing a library, but I'm not sure which one. Anyone know?</p>
