A test will follow. I've looked at the code and the problem seems to be that RowGroupDataSource shares data with its copies, so that the rows are not always recomputed when needed. I think I can fix this by making more use of immutability, something I was gonna try anyway for the re-implementation of the "flow into footer" feature.
