Flex DataGrid with CF dataprovider and Undo/Redo
Hi Flex is new to me but I'm having fun setting up a datagrid with a CF dataprovider. It works well so far and I have the CRUD functionality I need, however if possible I'd like to add a system of undo/redo on the grid. I was thinking of maybe intercepting each query in the cfc and serialising a WDDX packet recording the pre-edit state of a cell and storing it in a database table so that I can rewind each change. Or is there some built in Flex functionality I don't know about? Any ideas? Thanks Brian ~| Want to reach the ColdFusion community with something they want?

Using the DataManagement service, you can control database commits and cancel them, and each record is sent to the server as a ChangeObject, which contains old and new values.
