[jboss-dev-forums] [Design of JBoss jBPM] - get a token in another task

Hi everybody . I have a problem to go to next task-node with jbpm in a web application by using struts. i did a small process like this: anonymous wrote : start | task1 | task2 | end On my first bean in strut, i deploy process and i go to the first task. But when i write this in order to go to the next task: anonymous wrote : | TaskMgmtSession taskMgmtSession = jbpmContext.getTaskMgmtSession(); | | TaskInstance taskInstance = taskMgmtSession.loadTaskInstance(1); | taskInstance.setActorId(jbpmContext.getActorId()); | taskInstance.start(); | | Token token = graphSession.loadToken(1); | Transition transition=null; | String transitionName=null; | | if (token.getNode().getLeavingTransitions().isEmpty() == false) { | Iterator availableTransitionsIterator = token.getNode().getLeavingTransitions().iterator(); | while (availableTransitionsIterator.hasNext()) { | transition = (Transition) availableTransitionsIterator.next(); | } | transitionName=transition.getName(); | } | | token.signal(transitionName); | ProcessInstance processInstance = token.getProcessInstance(); | | jbpmContext.save(processInstance); | there are an error : anonymous wrote : | Integrity constraint violation - no parent FK_TASKINST_TASK table: JBPM_TASK in statement [insert into JBPM_TASKINSTANCE (NAME_, DESCRIPTION_, ACTORID_, CREATE_, START_, END_, DUEDATE_, PRIORITY_, ISCANCELLED_, ISSUSPENDED_, ISOPEN_, ISSIGNALLING_, ISBLOCKING_, TASK_, TOKEN_, SWIMLANINSTANCE_, TASKMGMTINSTANCE_, CLASS_, ID_) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, 'T', null)] | what's this error means ? i think it can't execute *.signal() why ?
