Cairngorm... data provider to the grid is an ArrayCollection. Adding items to the list works, databinding operates, things look OK.
http://budgetapp-uat.gameteamlead.com/bin/demonstrate_datagrid_itemEditor_displaylag-debug.html Editing items in the list, not so much. Like it says on the screen: This test program shows a Flex DataGrid dataBinding failure. Click Add LineItem a few times. Then edit one or two of the items. Your edits only appear visually after sorting on column 1. Putting a breakpoint on the MouseUp code and inspecting the model.ModelLocator shows the data is in there, but it's not on screen. Click View source to see the fancy code. H A Y U L P !!!
