My table Person have a PK called PersonId which is uniqueidentier, not null, rowguid - true, and a default value of newsequentialid().

When I try to save a record using self-service 2.5 llblgen complains that PersonId can not be null, however dont want to generate the guid in my code but have sql do that.

Is there an option I have to enable?

My bad again.. SQL SSMEX throws a validation error if you use newsequential, without reading this I clicked Yes (presuming it would force it), however the actual question is do you want to remove the change or something to that effect.
