Hi,

Master detail relations (with TIBOTables) doesn't work when the
fieldnames of the masterfields and the detail fields are different.
In the "GetValuesFromMaster" method is utilized the same
"FieldName"
to "FindField" both in "tmpDataSet" and
"Self" with the net result of
assign the incorrect value to the detail field of the new record.

I hope this helps.

Un saludo
Francisco
