First iI modify my code in order to delete the jbpmsession, I use now just the jbpmcontext. For creating an processInstance I try to put just after a creation of process instance " Collection processinstances=graphSession.findProcessInstances(pd.getId());" but I have an error of transient unsave. SO I move my loop which return my process instances before. But I have 3 instances of portlets on my portal so I must have some porcess instances whne I execute it but my collection of process instances id is always empty... how can I resolve it. thank you for you help antitrust1982 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3972836#...
