Amy, I have a request. Please consider placing your response above the history? You have good stuff to say, but always having to scroll through the history is aggravating, and provides no value.

OK, I got the bright idea that I would composite the existing class with a new class that has a uid. The class looks like this: package com.magnoliamultimedia.vo { import mx.core.IUID; import mx.utils.UIDUtil; public class TaskUID implements IUID { private var _task:Task; private var _uid:String; public function TaskUID(task:Task) { _task=task; _uid:UIDUtil.createUID(); } public function get uid():String { return _uid; } public function set uid(value:String):void { throw new Error("Can't directly set UID"); } public function get task():Task{ return _task; } } } The problem is that as soon as the ADG loads, I get a ton of "Can't directly set UID" errors. I thought Flex was _not supposed_ to set UID's on classes that implement IUID? Note that this is not a visual clas, these are typed objects in an ArrayCollection of typed objects that have ArrayCollections in them named children (HierarchicalCollection). If Flex is adding a UID to my objects, is there any way I can tease it out to use it to determine the parent? Thanks; Amy
