hey, Well as you can see from my handler code above that is the only way I could get GraphSession.deleteProcessInstance to delete the ProcessInstance and to have the cascades work correctly. The case i have is that Comment objects are attached to tokens in the process instance. Basically I had to clean out all references to the Comments everwhere manually as you can see from my code. Without this 'cleanup' code I get exceptions back from hibernate basically telling me there are references on Comment instances left so the delete fails. Regards, Leo "mputz" wrote : Leo, the GraphSession.deleteProcessInstance method *should* handle all references correctly, and should thus get rid of all data related to a process instance. If it does not, it would be great if you could provide more info about what is missed out, so that this can be fixed.
