title: In what case does jQuery sortable fail silently?
body: <p>I've been trying to see why a certain jQuery <code>.sortable()</code> will not enable any drag/drop events in some circumstances - In a certain jQuery dialog I have a sortable, I confirm that the element exists while debugging (<code>$('theelement')</code> is length 1, just before calling <code>$('theelement').sortable()</code>).</p>
  
  <p>I verify the events are there, with Chrome's inspector, and I can't see any reason it wouldn't be doing the exact same code that is working in another jQuery dialog, in which allows drag-drop reordering. I've removed classes of the container to make it similar to the one in which it works, in case something like <code>jQuery('.something theelement').mouseup(function(){return false})</code> is firing.</p>
  
  <p>I've also simplified the code by changing the sortable to something as simple as</p>
  
  <pre><code>&lt;ul target element&gt;
    &lt;li&gt;test&lt;/li&gt;
    &lt;li&gt;test&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>and calling <code>jquery(target element).sortable()</code> so it shouldn't be some complex css or dom issue causing this.</p>
  
  <p>Is there anything other than debugging each step through each line of the minified jQuery-ui source, to find the source of this problem?</p>
