    history problem

    jeffery c Newbie

      i have created a process like this:

      JbpmConfiguration environmentFactory = (JbpmConfiguration) getEnvironmentFactory();
      ProcessService processService = environmentFactory.get(ProcessService.class);
      ClientProcessDefinition processDefinition = ProcessDefinitionBuilder
       .startProcess("branch_history_problem")
      
       .startActivity("start", WaitState.class)
       .initial()
       .transition("forkNode")
       .endActivity()
      
       .startActivity("forkNode", ForkActivity.class) // just as org.jbpm.jpdl.internal.activity.ForkActivity
       .transition("leftWait", "to_left")
       .transition("rightWait", "to_right")
       .endActivity()
      
       .startActivity("leftWait", WaitState.class)
       .transition("leftLogic")
       .endActivity()
       .startActivity("leftLogic", WaitStateMaybeExceptionThrowout.class) // may throw out exception or call wait for signal, call historyXX inside
       .transition("join")
       .endActivity()
      
       .startActivity("rightWait", WaitState.class)
       .transition("rightLogic")
       .endActivity()
       .startActivity("rightLogic", WaitStateMaybeExceptionThrowout.class)
       .transition("join")
       .endActivity()
      
       .startActivity("join", JoinActivity.class) // just as org.jbpm.jpdl.internal.activity.JoinActivity
       .transition("end", "to_end")
       .endActivity()
      
       .startActivity("end", AutomaticActivity.class)
       .endActivity()
      
       .endProcess();
      
      /*
       / leftWait(wait state) - leftLogic(wait state) \
      start(wait state) - forkNode join - end
       \ rightWait(wait state) - rightLogic(wait state) /
      */



      then, i created a process instance and made it run,
      when the acitivty moves to Activity("leftLogic", WaitStateMaybeExceptionThrowout.class) or Activity("rightWait", WaitStateMaybeExceptionThrowout.class)
      exception throw out:

      Cannot add or update a child row: a foreign key constraint fails (`jbpm_pvm/jbpm_hist_actinst`, CONSTRAINT `FK_HAI_HPI` FOREIGN KEY (`HPI_`) REFERENCES `jbpm_hist_procinst` (`ID_`))
      insertSQL= "/* insert org.jbpm.pvm.internal.history.model.HistoryActivityInstanceImpl */
      insert into JBPM_HIST_ACTINST
      (DBVERSION_, HPI_, ACTIVITY_, EXECUTION_, ACTIVITY_NAME_, START_, END_, DURATION_, TRANSITION_, CLASS_) values (?, ?, ?, ?, ?, ?, ?, ?, ?, 'ACT')"


      then i modify the method ActivityStart#process as follow, it seems work ok...
      .....
      public void process() {
      Session session = Environment.getFromCurrent(Session.class);
      
      // modification begins
      org.jbpm.pvm.internal.model.ExecutionImpl tmp = execution;
      while(tmp.getParent() != null){
      tmp = tmp.getParent();
      }
      // ends
      
      HistoryProcessInstance historyProcessInstanceImpl = (HistoryProcessInstance)
      session.load(HistoryProcessInstanceImpl.class, tmp.getId()/*execution.getId()*/); //..
      
      HistoryActivityInstanceImpl historyActivityInstanceImpl =
      createHistoryActivityInstance(historyProcessInstanceImpl);
      
      session.save(historyActivityInstanceImpl);
      
      execution.setHistoryActivityInstanceDbid(historyActivityInstanceImpl.getDbid());
      }
      .....


      is there something i missed or?
