    Signal Error

    m owens Newbie

      Could anyone please explain why this code throws the following exception: "closed JbpmContext in different order then they were created... check your try-finally's around JbpmContexts blocks".

      Code:

      public JbpmProcessInstance(JbpmProcessDefinition processDef, bpmProcessInstanceVar var)
      {
      beginSessionTransaction();
      try
      {
      ProcessDefinition processDefinition = jbpmContext.getGraphSession().loadProcessDefinition(processDef.getId());

      // create a new process instance to run
      processInstance = new ProcessInstance (processDefinition);

      if(var!=null)
      addProcessInstanceVar(var);

      processInstance.signal();
      }
      catch (Exception e)
      {
      log.error(e.getMessage());
      throw new JBPMException(e.getMessage(),e);
      }
      finally
      {
      commitAndCloseSession();
      }
      }

      The error is thrown on the signal() line. I have tried to find a reason for this for a number of days and as a result of not being able to am now loooking at other workflow solutions. could someeone please point me in the direction of an explaination so i can continue using JBPM?

      Thanks

          JBPM signalling doesn't work. I tried to decorate JBPM objects into more manageable strcture but the context kept going out of skope or reporting invalid creatiun states. I think this will going to be fixed in the next release.

            @scitmon: why do you come to this conclusion?

              because i have tried many different ways to get JBPM working and signalling always causes error with the following text "closed JbpmContext in different order then they were created... check your try-finally's around JbpmContexts blocks". The CVS tests don't seem to work either. There is no help files they explain how to do this.

                CVS tests don't work? You mean the jbpm unit tests? They work for me and I only have had this error when things were not programmed correctly or the transaction configuration was not ok. So jBPM signalling *does* work.

                We need a more specific and isolated example, including transaction config, hibernate config jbpm config, good code etc... to be able to help. Just a statement like 'jbpm signalling does not work' does not help, including 'tried many different ways'. I've used it in two different ways and did not get this error....
