Unfortunately not. I have no idea why. I 'solved' this issue by having transactional spring dao classes do _everything_ for me, i.e. something like: myDao.addLogToJob(LogItem log, Job job) { job = em.find(job.getId()); job.getLogs().add(log); em.merge(job); } Ugly and bad in every way possible, but at least it worked and was ready to deadline... :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4124295#...
