title: WinJS.Namespace defined methods not accessible
body: <p>I have a navigation app. In the page Control corresponding js files are present. I want to access an external js file which is in the project js folder. I have specified in </p>
  
  <p>commonFunctions.js</p>
  
  <pre><code>WinJS.Namespace.define(
  
  'commonFunctions', {
  
          authenticate: authenticate
  
      });
  </code></pre>
  
  <p>Now when accessing the method in the PageControl's js (page2.js) file</p>
  
  <p>commonFunctions.authenticate();</p>
  
  <p>it gives an error:</p>
  
  <p>0x800a1391 - JavaScript runtime error: 'commonFunctions' is undefined</p>
  
  <p>If there is a handler for this exception, the program may be safely continued.</p>
  
  <p>Is this the right way to do this? Or am I missing something?</p>
