Charlie,
Mike was using table buffering. The problem was when a requery was done of the grandchild view when the child record changed. Even using table buffering, requerying a dirty view throws an error.

And I disagree with "binding data directly to a grid causes headaches". IMO, it simply requires a different approach. I'm sure you had initial headaches when you attempted to implement your listbox-array approach. You probably don't now because you have worked through them.
