body: <p>How to make popup window in Liferay?
  This my code. It's like in Liferay Wiki.</p>
  
  <pre><code>var popup = new Liferay.Popup( { 
    header: 'our title', 
    position:[150,150], 
    modal:true, width:500, 
    height:300, 
    xy: ['center', 100], 
    url: '/my_file.jsp', 
    urlData: { winowState : 'LiferayWindowState.EXCLUSIVE'} 
  } );
  </code></pre>
  
  <p>What is missing?</p>
  
  <p><strong>PS: I'm trying to put it working in  Liferay 6.0</strong></p>
