Try removing the root node from the tree and then reinserting each
of it's children back into the tree. This works for me:
<code>
// Attach the XML data provider
myTree.dataProvider = myXML;
// Remove the root node from the tree object
var node = myTree.removeTreeNodeAt(0);
// Reinsert each of the root node's children in the tree
var n;
while (n = node.firstChild) {
myTree.addTreeNode(n);
}
</code>
