I want to use a timestamp for concurrency control and I can't figure out how I should configure the timestamp field in the BO Mapper. Whatever I try causes either compile or runtime errors. What is the recommended way of configuring a timestamp in the BO Mapper and is there anything I should be doing in _SetDefaultValues to set an initial value for a new record?

Cheers, Peter

In this case you would probably want to increment rather than decrement it...but otherwise, yes.
