title: Editing languages in siteadmin/preferences in AEM
body: <p>I am trying to change the list of languages in the Admin preferences. I referred to this page: <a href="http://www.wemblog.com/2012/06/how-to-add-new-supported-language-in-cq.html" rel="nofollow">http://www.wemblog.com/2012/06/how-to-add-new-supported-language-in-cq.html</a>
  I am able to get the list of languages but each time I get languages like Arabic or Amharic (which are not there in libs) I get the following error in the <code>moment.js</code> file.</p>
  
  <blockquote>
    <p>Uncaught TypeError: Cannot read property 'postformat' of null </p>
  </blockquote>
  
  <p>This is only there in Touch UI mode. In Classic mode it is not showing any error.</p>
