[flexcoders] Re: sending user selections back from TitleWindow to itemRenderer (parent) - how

[barry.beattie]

LOL! thanx anyhoo, Doug.

I can guess that all I need to do is get a reference to the origional
ArrayCollection (the dataGrid's dataProvider) from within the
titleWindow and let the [binding] do the rest... but it's a read then
append then save.

I've tried but keep getting scoping issues.... from the titleWindow's
point of view the ArrayCollection is in the parent's parent. 

my code (so far) for the itemRenderer and titleWindow are in my
origional post but I'll throw it in here (in desperation)

(cheers, mate)

anyone else suggest how to do this?

much appreciated
thanx
