          What are you trying to send in ContentData? Are you sure that all the objects there are serializable?

                    The debugmode shows me, that the manager (manager.completeWorkItem(task.getTaskData().getWorkItemId(), results);) is null, but i dont know how to change it.

                    I use jbpm 5.3 Final with jboss as 7.0.

                     

                    I hope someone can help :-)

                      I think that this bug is already fixed in master.

                      Can you use the latest snapshots?

                      Cheers

                        I changed to 5.4-SNAPSHOT and now i get a new exception:

                          Oh sorry,

                          i forgot to change the drools-version.

                          Now it works with jbpm 5.4-SNAPSHOT and drools 5.5-SNAPSHOT

                            My code is:

                             

                            AsyncGenericHTWorkItemHandler taskHandler = new AsyncGenericHTWorkItemHandler(session);

                            Field f = AsyncGenericHTWorkItemHandler.class.getDeclaredField("manager");

                            f.setAccessible(true);

                            f.set(taskHandler, session.getWorkItemManager());
