Hmmm, then we could implement it so that the save() method of the Torque objects and the doUpdate() method of the Peers use optimistic locking only if the versionProperty attribute is present. I guess this should be discussed on torque-dev if anyone wants to implement it... -- Rodney -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
