So I am trying to use Hibernate OGM (4.1.0.Beta4) with MongoDB, now I have run into this issue which is confusing me, so I get a list of my entities I created, then I try to cycle through that list and delete each one - however when I try that I get the following exception "Removing a detached instance", I am assuming I have missed something with the persistence setup.

I guess the major thing I am confused about is withing deleteAllTests() I get the list of entities, then try to delete them but they are detached already? So I am clearly missing something fundamental as well, my suspicion is that its mongo-ogm and JTA not playing nice because mongo is not transactional, but I figured ogm would abstract that for me.
