title: Liferay Application Display Template - Get Velocity variables
body: <p>I am writing an Application Display Template for an Asset Publisher in Liferay (6.2 GA5) in Freemarker and I want to display the author and the creation date. A while ago I needed the same variables for a template and I found matching Velocity variables: 
  <code>$reserved-article-author-name</code> &amp; <code>$reserved-article-create-date.data</code></p>
  
  <p>To use Velocity variables in FreeMarker, I called them like this: <code>${.vars['reserved-article-author-name'].data}</code></p>
  
  <p>In my Template, it works fine, in my ADT, it throws an error: </p>
  
  <blockquote>
    <p>Expression .vars['reserved-article-author-name'] is undefined</p>
  </blockquote>
  
  <p>How do you manage to get these variables to work in my ADT or is there an alternative way to get this information?</p>
