Hi,

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

Hi,

For anyone interested setting the timestamp column in the BO Mapper to "Return Alternate on Null" with a return value of "Nothing" seems to work ok.

Cheers, Peter

I just saw your two posts and you are correct.  You have to use Return Alternate on NULL rather than a Nullable Generic.  You can return nothing, or return a "default" date such as "1/1/1800."
