As stated this morning (or noon).

If you use the OnDataChange event of the MasterDataSource and check for
not assigned field (otherwise this event will also fire whenever you're
moving horizontally (ie from field to field) within your grid) you can
be sure this will be triggered even if you're a re-open on the
MasterQuery (which of course shouldn't trigegr an OnAfterScroll, you're
right).

Then the DataSource of the master (which is a detail now, too) will
change, when changing the "super-master".
Still it will work.
