title: displayTag: how to change displayTag parameters
body: <p>I want to change the ugly displayTag (tableid) parameter from <code>d-bunchofnumbers-p</code> to a URL friendly one. I also want to change the sort and page parameters as well.</p>
  
  <p>Is it trivial to do this?<br>
  If so, how? Is it as simple as setting the following properties? </p>
  
  <pre><code>&lt;display:setProperty name="pagination.pagenumber.param" value="page"/&gt; 
  &lt;display:setProperty name="pagination.sort.param" value="sort"/&gt; 
  &lt;display:setProperty name="pagination.sortdirection.param" value="dir"/&gt; 
  </code></pre>
  
  <p>The URL should look like this:</p>
  
  <pre><code>results?sort=id&amp;dir=asc&amp;page=1
  </code></pre>
  
  <p>I've tried this but, it's not working. Thanks! </p>
