Are you using Session.update()? Use Session.merge() instead. It should
solve your problem.
Yes I am, but this method (the one I call on tapestry code) is on a
"base" core code that my app uses, I can't change it.
Well, your core code isn't using what it should. In my Generic
DAO-Hibernate package, I used update() and I tried many ways to avoid the
"a different object with the same identifier value was already associated
with the session:...". No one worked. Now my package uses merge(). JPA
doesn't have an update() method, just merge().
