title: extjs 4.1.0 controller's init function won't be called
body: <p>I'm fairly new to both javascript and extjs and I encountered this problem while trying to run through the steps of the extjs 4.1 MVC Architecture tutorial. Evereything works fin in the beginning but when I try to add the controller to the application something goes wrong. Neither the applications launch function nor the controllers init function is called. I used the sample code from here <a href="http://afsweb.ms.com/ms/dev/ria/ext/4.1.0/src/ext-4.1.0-gpl/docs/index.html#!/guide/application_architecture" rel="nofollow">here </a> but I couldn't get the 'defining a controller' step working. It finds the Users.js there's no error message, still it won't call the controllers init function. If I remove the 'controllers: ['Users'],' the applications launch will be called. Any ideas what I'm missing?</p>
  
  <p>app.js:</p>
  
  <pre><code>Ext.application({
  requires: ['Ext.container.Viewport'],
  name: 'Account Manager',
  
  appFolder: 'app',
  
  controllers: ['Users'],
  
  launch: function() {...}
  </code></pre>
  
  <p>Users.js:</p>
  
  <pre><code>Ext.define('app.controller.Users', {
  extend: 'Ext.app.Controller',
  
  init: function() {
          console.log('Initialized Users!');
  }
  });
  </code></pre>
  
  <p>Thank you for your time.</p>
