Lars Bohl commented on AS7-2781:
--------------------------------

Scott, the attached application was created for the sole purpose of demonstrating this "bug". It is based on jboss-javaee6-webapp, see http://community.jboss.org/thread/175674. However, I ran into these problems when trying to migrate an existing in-house webapp from jboss 6.1 / jboss seam 2 to jboss 7. Maybe seam-persistence (http://seamframework.org/Seam3/PersistenceModule) makes the problem disappear by creating a transaction around each request, or maybe not. I will look into this later.

> After entityManager.find(), the session appears to be closed (can't access persistent collection). A functionally equivalent query for id works fine.
