[flexcoders] Re: expandable itemRenderer with state inside a list
Thanks tracy. It works now...But the behavior of the scrollbar when scrolling is annoying. It resizes itself all the time. I suppose that items that are no longer visible are removed from the displayList. This behavior is ok when all items have the same height. have u any idea to change this? --- In flexcoders@yahoogroups.com, Tracy Spratt [EMAIL PROTECTED] wrote: Ah, yes, I'd read your post, but hadn't thought through the logic to see that set data would need to be called on resize.

RE: [flexcoders] Re: expandable itemRenderer with state inside a list
Sorry, that level of graphics behavior is beyond me. Maybe someone else will help. If no one helps on this thread, start another topic with this current issue.
