[flexcoders] Using An Array Collection Produced From XML In Conjunction With Shared Object

[James]

I have an old app which allows the user to drag items between two tilelists and 
then save the contents of both tilelists by clicking a save button using the 
sharedObject method. The tilelists are populated by array collections defined 
in the app. I want to change this so that the tilelists are instead populated 
by an array collection which I've retrieved from a remote xml file via http 
request but I can't get this to work. Basically I need to replace both the 
predefined array collections profile1NewsAndSportaddLinksFullAC and 
profile1NewsAndSportaddLinksAC with my xml/httprequest produced newsAC array 
collection and still make the tilelists saveable. Can anyone help me out? 
Here's the code:-

creationComplete="newsService.send(); initprofile1NewsAndSportSO()">
