Q. When using the table-per-subclass inheritance mapping, if you have mapped the parent to use the version element for optimisitic locking, we are assuming that you do not need to add a version element to the subtype's mapping, since when you update an instance of the subtype the version property should be updated in the parent's table. Is this correct?

Thanks, Kevin
