Hi,

I have a mxml class that extends ComboBox but using a tree instead of the usual list to show the data

<mx:dropdownFactory>
     <mx:Component className="comboTreeComponent">
        <mx:Tree creationComplete="outerDocument.expandTree(event);" change="outerDocument.updateLabel(event)" height="300" width="500" />
     </mx:Component>
    </mx:dropdownFactory>

now my expandTree function is not able to talk to the tree, how do i call into this component from the containing class?  i added the ID for the classReference and read a bunch of docs on the subject but I still have no idea how to reference into an item renderer.

btw, the goal here is to expand all items in the tree when the tree loads- if there's an easier way than this- i'm all ears :)

thanks,
d.
