Mx:tree not updating dynamically

Question

Hi
I am trying to simulate a directory structure through a tree
representation. I use a cfdirectory call through a RemoteObject and
attach the result to an XML object which then becomes the tree
dataprovider. The first time the tree opens fine with all directory
nodes. Each time I chose a directory to fetch the underlying
subfolders the tree component becomes messy as if the tree does not
refresh dynamically.
I am doing something wrong. Any ideas would be very welcome.
var mytree_struct:XML;
private function buildtree ():void {
for (var i:int = 0; i < aResult.length; i++) {
var newnode:XML = new XML();
newnode = <directory label={aResult.getItemAt(i).Name}
isBranch="true"> </directory>;
mytree_struct=mytree_struct.appendChild(newnode);
My tree event handler which should add new nodes (
subfolders) of the selected folder. For the moment I am just trying
it out with a test variable k.toString().
public function treeChanged(event:Event):void {
for (var k:int =0; k <10;k++ ) {
var newnode:XML = new XML();
var temp1:String = k.toString();
newnode = <subdirectory label= {temp1}
isBranch="true"> </subdirectory>;
event.currentTarget.selectedItem.appendChild(newnode);
}
