Thank you very much Tracy. What do you suggest to show/hide specific items based on an outside event? I am hesitant to *remove* the item from the ArrayCollection as I have to add it back at some point, maintaining the same complicated sort order. Currently my ArrayCollection contains a list of custom objects, would you suggest I had a property to those objects called *isHidden*, or something along those lines, and use that to set the state to "hidden"?
Thanks a lot.
