Pete, for us, this is a critical/blocking bug and the status should be set to "blocker" in JIRA. The code is running well on seam 1.2.1, and this problem forces us to wait until seam 2.0.1 is out before migrating to seam 2.0... I'm sure they are lots of projects ou there that are using plain POJOs for persistence that will have the same problem.
