Sorry for the delay.
Can you please elaborate on what you need to do?
Any checks that are done by NH (not-null, uniqueness, version etc.)
are only performed while flushing. Calling Save() won't do anything
within a SessionScope when the object is already persistent (this is
the case when you use ARDataBind).
My preferred option to handle this is calling Flush() manually,
catching errors and evicting the offending objects in the exception
handler.
