[jboss-user] [EJB 3.0] - Newbie Entity Question - changes visible in another instance

[lpmon]

Environment: Inside one JVM (JBoss AS 4.0.5 w/EJB3)

If a managed entity instance is held by thread A and thread B makes and saves changes to another managed instance will those changes be visible the next time thread A accesses its copy?

If answer is 'no' one might ask why not do a merge in thread A to get latest copy? 

Answer: in my case I have many transient properties and they get lost if I use the new object returned from the merge.
