It would be best to use the itemUpdated instead of setItemAt/getItemAt. YOu may be having a timing issue where mainApp and/or myAC is not set yet. Trace statements or the debugger should help.

I haven't tried it yet, but all I've found that looks like a possibility, is to create variables in the parent, set those from the PopUp, and then run a function to perform updateItem() , for each value in the ArrayCollection row OR, delete the row, and add a new one. Both create issues with sychronizing front-end display items and backend databases. Please help ________________________________ Looking for last minute shopping deals? Find them fast with Yahoo!
