Hi all,
I have loaded a collection of managed objects, made some changes to
one of them, and called the DataService.commit() to commit these
changes back to the database.
My DataService is connected to a HibernateAssembler destination, and
this destination worked to create the initial version of the objects,
however when I attempt to update them, I get this exception. I can
tell there was a data sync conflict (not sure why, I'm only using one
client, one session, one update to the object). However what concerns
me more is that it's attempting to do something afterwards, and I get
this Hibernate exception about the session being closed. Any ideas?
thanks in advance,
Thunder
