That is not normal behavior. Typically such updates happen nearly instantly.
First, are you using custom itemRenderers? If so, how many are visible at any one time? Are they optimized for performance, or are they based on a container, like Vbox? Next, you understand that when you do: mccert_refund_grid.selectedItem.CERTPRESENT = "NOT PRESENT"; you ARE updating the dataProvider? selectedItem is a reference to a dataProvider item. If you want to be able to provide an "undo" capability, you will need to make a copy of the data before allowing the user to modify it. Debug to find out where the speed bottleneck happens. Simplify the conditions until the problem goes away, then re-apply functionality until the problem returns.
