As for this problem, try using this
myTree.dataProvider = myTreeDP.firstChild;
It may work depending on the structure of your xml (with a root node) - it works
perfectly for me.

Subject: Re: [Flashcoders] Flash Shortcutting my XML
That's a good idea. I'll play with that concept. One other item of note
(just for others searching for similar issues) that I've found is that in my
onLoad function I set the dataProvider of myTree equal to the incoming XML
as such:
myXML.load("somefile.xml");
myXML.onLoad = function (){
myTree.dataProvider = myXML;
}
where somefile.xml is:
<item label="SubFolder1">
<item label="Cursors"></item>
<item label="SubFolder2">
<item label="SubFolder3"></item>
</item>
</item>
That produces the problem we've been discussing. Using the method I
explained about changing the leaf icon works except that the disclosure icon
( + or - ) does not show up. However, the following code produces the
correct results in the tree (disclosure icon and all):
var newXML = new XML("<item label=\"New Folder\"></item>");
newNode = mainNode.addTreeNode(newXML.firstChild);
OR
var newXML = new XML("<item label=\"New Folder\" />");
newNode = mainNode.addTreeNode(newXML.firstChild);
So it seems that adding a node with the </item> or the <item label="New
Folder" /> tags works fine using the addTreeNode function, but assigning the
XML using dataProvider does not.
I'm going to try just looping through the XML adding each node individually.
That should work, but I'm not sure of the speed in which I will be able to
accomplish what I'm trying to do especially when there are hundreds of nodes
I'm dealing with.
