ok I have found the solution myself, it might interest other people though :: I had a one-to-one relation (defined on the primary key) between my Client class and my Account class the getId() of my Account had the annotation @GeneratedValue but I forgot to put the same annotation to Client which causes my entries in the DB to end up with different Ids. This apparently was causing a problem...but I am not pretty sure it was linked to the ending of the conversation. Does someone know a way of visualising the current conversation so that one can check they are ending properly ? cheers View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4087396#...
