Linda,

>I think I understand your instructions but I can't seem to get them to work. When I use the MM .NET busines layer generator, the value of the date field in the entity already has the date of 12/30/1899 and does not evaluate as a null value. (I tested for entityobject.datefield is dbnull and got a warning that it can never be null.) I notice that the business object uses a function GetNonNullableDbValue to load the field value to the entity object. Can I change that to test the value there?

Is the database column nullable?

Best Regards,
