[jboss-user] [EJB 3.0] - Need advice on refreshing @Version column

[treespace]

I need to merge changes an entity instance multiple times. The second merge causes an optimistic lock failure unless I "manually" update the version string:

original.setVersion( em.merge( original ).getVersion() );

I cannot use the updated entity returned from merge because I have many reference to the original instance in several lists. 

Calling em.refresh( original ) after em.merge( original ) did NOT update the @Version column.  Why doesn't refresh update the version column?
