title: Why doesn't a newly added UL accept Drag'n'Drop?
body: <p>I am using Dojo's Drag &amp; Drop functionality to create a sortable mutlidimensional list.</p>
  
  <p>Now, when I added code that will spawn a new UL inside a hovered LI when dragging something onto it, the newly spawned UL won't accept items to be dragged into.</p>
  
  <pre><code>dojo.addOnLoad(function ()
  {
      dojo.query(".listview").forEach(function(node, index, arr)
      {
          dojo.connect(node, "onmouseover", "ListViewInsertList");
          dojo.connect(node, "onmouseout", "ListViewInsertListAbort");
      });
  });
  
  var hovernode = null;
  var timeout = null;
  
  function ListViewInsertList(e)
  {
      console.log("Hover caught.");
      if (dojo.query(".dojoDndAvatar").length &gt; 0)
      {
          console.log("DND is active!");
          hovernode = e.target;
          timeout = window.setTimeout("ListViewInsertListDo()", 1000);
      }
  }
  
  function ListViewInsertListDo()
  {        
      dojo.create("ul", { dojoType: "dojo.dnd.Source", className: "container listview" }, hovernode);
  
      dojo.query(".listview").forEach(function(node, index, arr)
      {
          dojo.connect(node, "onmouseover", node, "ListViewInsertList");
          dojo.connect(node, "onmouseout", node, "ListViewInsertListAbort");
      });
  }
  
  function ListViewInsertListAbort()
  {
      window.clearTimeout(timeout);
  }
  </code></pre>
  
  <p>My HTML looks something like this:</p>
  
  <pre><code>&lt;ul dojoType="dojo.dnd.Source" selfAccept="true" class="container listview"&gt;
       &lt;li class="dojoDndItem listviewitem"&gt;abc&lt;/li&gt;
       &lt;li class="dojoDndItem listviewitem"&gt;def
            &lt;ul dojoType="dojo.dnd.Source" selfAccept="true" class="container listview"&gt;
                 &lt;li class="dojoDndItem listviewitem"&gt;ghi&lt;/li&gt;
            &lt;/ul&gt;
       &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>So how do I tell Dojo, that the newly added UL is good for items to be dropped into?</p>
