     *  to other occurences of the same node in the tree.  The only way to obtain an unambiguous

     * com.smartgwt.client.widgets.tree.Tree#getPathForOpenListIndex getPathForOpenListIndex()},

     *  the node occurence is not yet in the tree's openList - either because its parent has not yet
     *  been opened, or because the tree is in the process of being built - the tree is not able to 
     *  provide a path to the node occurence.  In this case, you would have to obtain the path

     * is the default <code>/</code> and <code>foo</code> is the name of the root node, then

     * your tree nodes had a unique field called "UID", their serialized form would look something like this: <pre>
     * { name: "foo", children: [...], UID:"someUniqueId"} </pre>  You could then call <code>tree.find("UID",
     * "someUniqueId")</code> to find that node.  Note that the value doesn't have to be a string - it can be any
     * valid JS value, but since this data generally comes from the server, the typical types are string, number,
     * and boolean. <br><br> The usage where you pass a single object is interesting when your tree nodes have a
     * number of custom properties that you want to search for in combination.  Say your tree nodes had  properties
