title: How best to add this Action Helper path in Zend Framework
body: <p>I have written a custom ACL class as an Action Helper.  The class name is Controller_Helper_Acl, and is located in the file applications/controllers/helpers/acl.php.  My problem is that my application is having difficulty locating the file.</p>
  
  <p>I want to use the Action Helper Event Hooks, so I need to instantiate the class early.  In my bootstrap.php I tried the Helper Broker's addPath() method, but that doesn't work when I use the new keyword.  (Presumaly it just tells the broker where to find the files when the class is called on demand).</p>
  
  <p>If I put a require_once in the bootstrap, then use the new keyword to instantiate Controllers_Helpers_Acl, it works fine, but I don't think this is a workable solution (since I will have many Action Helpers in the directory).</p>
  
  <p>I tried adding a path to the Autoloader with $loader->registerNamespace('Controllers_Helpers_'), and pluralizing the class name, however file is still not found.  (Perhaps I have the wrong syntax?)</p>
  
  <p>How do others solve this problem?  I suspect that it's my inexperience with Autoloader that's the real problem.</p>
