OK, after some digging, there is another problem: the code in
setChildLinkFilter(), starting around line 849, reads:
if self.DataSource and self.LinkField and self.Parent:
if self.Parent.IsAdding or self.Parent.RowCount == 0:
# Parent is new and not yet saved, so we cannot have child
records
yet.
self.setWhereClause("")
filtExpr = " 1 = 0 "

cannot have child records yet, is incorrect, since the child could be
based on some other field, as it is here? Can you see any problem with
changing the second line above to read:
if self.Parent.RowCount == 0:
