To view the discussion, visit: https://community.jboss.org/message/649669#649669 -------------------------------------------------------------- Hi all, I am new for jbpm. I have passed *boolean value* to the variable name "*qcapproval*". I used *constraints* in bpmn diagram, in that if the variable *qcapproval == true* the process end. otherwise (that is *qcapproval == false*) process continue. But I need to change the variable value as *true dynamically*. Because if i set the variable false loop continues. I need to stop the process in the particular stage. So i need to change the variable value as *true dynamically*. Kindly advise me. I have attached my code below. *Code:--    *             StatefulKnowledgeSession ksession = createKnowledgeSession("Print.bpmn");             Map<String, Object> params = new HashMap<String, Object>();             params.put("qcapproval", false);             TaskService taskService = getTaskService(ksession);             ProcessInstance processInstance = ksession.startProcess("com.tnq.workflow.jobflow.Print.bpmn", params);             assertProcessInstanceActive(processInstance.getId(), ksession); Thanks for looking into this.... -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/649669#649669] Start a new discussion in jBPM Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
