Vladimir Stankovic [https://community.jboss.org/people/svlada] created the discussion "I am getting Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [org.jbpm.task.Task#1]" To view the discussion, visit: https://community.jboss.org/message/793555#793555 -------------------------------------------------------------- I am trying to create simple process and register simple Human Task handler. Exception occurs when I try to start process. Any idea what problem could be? All required users => "Administrator" and "svlada" are already in database. Here is my source code {code} // Prepare input process params Map<String, Object> params = new HashMap<String, Object>(); params.put("income", 150); params.put("user_id", "svlada"); // Create Task Session - responsible for adding new users to db TaskServiceSession taskServiceSession = this.getSpringTaskSessionFactory().createTaskServiceSession(); addUsersAndGroups(taskServiceSession); MockUserInfo userInfo = new MockUserInfo(); // Start and create new process instance ProcessInstance processInstance = ksession.createProcessInstance("com.sample1.bpmn", params); // Register human task handler LocalHTWorkItemHandler taskHandler = new LocalHTWorkItemHandler(getLocalTaskService(), getKsession()); ksession.getWorkItemManager().registerWorkItemHandler("Human Task", taskHandler); // Start selected process instance System.out.println("State before: " + processInstance.getState()); ksession.startProcessInstance(processInstance.getId()); System.out.println("State after: " + processInstance.getState()); // Get Tasks assigned to user List<TaskSummary> tasks = getLocalTaskService().getTasksAssignedAsPotentialOwner("svlada", "en-UK"); {code} Here is my stacktrace {code} Hibernate: insert into WorkItemInfo (creationDate, name, processInstanceId, state, OPTLOCK, workItemByteArray) values (?, ?, ?, ?, ?, ?)
