As Tim guessed in his post, your two Acs share the same source, so are essentially one dataProvider.
Use concat() to make a copy of dp before you create bc.

Start with the DataGrid declaration mxml and the change handler function.

On select of an item in one grid I set the data['selected'] property accordingly and call an itemUpdated in the ArrayCollection. Can anyone think why a selection in one grid is also selecting an item in the second grid?
