[jboss-user] [EJB/JBoss] - Removing entity does not work!

[hamtho2]

Hi,

somehow removing entities does not work using the embedded JBoss for my tests. 

If I open my own transaction within my test-class and try to delete an entity, everyting works fine. If I call my SessionBean, having exactly the same piece of code, it fails. Even if I try to merge my entity before removing it, does not solve the problem and merge() does not throw an exception at all. This sounds like a very strange behaviour, so I was asking myself, if this might be an problem related to the embedded jboss. Does anyone know, if there is still a bug?

FYI: This is my stacktrace when trying to remove the entity within my SessionBean
