Has anyone solved this issue? We are getting this same issue with the upgrade to Seam 2.3.0 Final
This looks like a bug. Can you provide any reproducer by a chance? I assume that's same also for 2.3.1.Final....Did you try this?
I didn't try Seam 2.3.1 Final. We are at the end of a long upgrade from JBoss 4/Seam 2.1.1 to JBoss 7.1.1/Seam 2.3.0.
I did find somewhat of a workaround that is working for us. So in the action class that is mapped to the nested conversation, if I explicitly do an @In on the entity that ends up getting the StaleStateException the error goes away. I assume this brings the entity explicitly into the nested conversation. This allows us to get by this issue.
