Error "Cannot acces field "FIELDNAME" as type variant"

SDAC v. for Delphi 7 on Windows XP pro.
TMSTable connected through a provider to a mssql server 2005;
after inserting a record on a table containing a field with datatype BIGINT, (the provider ?) threw that exception.
The BIGINT field is not primary key, nor foreign key, not even have a constraint on it.

Debugging the application, appears that exception occurs after the execution of AfterUpdateRecord event, without a definite source line.
