By converted I meant migrated. I may end up having to restore the version 2 business objects and manipulating them manually, but that seems counter productive.

I tried creating a net new project and generating the business objects again and then just moving my code over. The result was the same. First off I selected dynamic SQL and the command type was still set to stored procedure and secondly the error persisted. When I issue a saverow I get the following error stream:

[NullReferenceException: Object reference not set to an instance of an object.]
