title: struts-jquery does not load dialog content
body: <p>Have this code:</p>
  
  <pre><code>&lt;sj:head compressed="false" jqueryui="true" jquerytheme="custom"/&gt;
  
   &lt;s:url id="link" action="ABC" namespace="/DEF" escapeAmp="false"/&gt;
   &lt;sj:a openDialog="_dialog" cssStyle="float:left;padding:5 0 0 10;"&gt;
                  Link
   &lt;/sj:a&gt; &lt;sj:dialog id="_dialog" href="%{link}" modal="false" resizable="false" 
                  position="center" closeOnEscape="true" draggable="false" title="Contact Us" autoOpen="false"&gt;
              &lt;/sj:dialog&gt;
  </code></pre>
  
  <p>And when I click the link - it opens the dialog, but the content is empty. And as I see there are no any request made to /DEF/ABC.action. </p>
  
  <p>But, if I change autoOpen attribute to true, - then the dialog opens once page is loaded, and content is there. </p>
  
  <p>What could be the problem, how can I make it work properly?</p>
