TIB_Query has a flexible Master/Detail relationship
via MasterLinks and MasterSource.

TIBOQuery is appears to be missing this and Master/Detail
link parameters seem to come from whatever matches an
internal pool by the same fieldname used in the Query
for the detail as 'field = :field', regardless the
settings of Keylinks and then only when paramCheck is
set to True, else I get an internal paramater mismatch error.

Trying to Master/Detail link two TIBOQueries say for
table A and B on Keylinks = B.Field1=A.Field2

Please straighten me out :)
