[jboss-user] [jBPM] - self-transition to node with timer crashes in 4.3

--------------------------------------------------------------
just as the name suggests. used to work in 4.0
issue is with duplicate entry in the execution DB - seems like the order of DB statement execution isn't right

any ideas of a workaround would be appreciated (adding an interim node and transitioning to it and then back is not desireable)

thanks in advance for ideas,
gelos

modified unit test shipped with 4.3 - TimerTransition

<process name="TimerTransition" xmlns=" http://jbpm.org/4.3/jpdl http://jbpm.org/4.3/jpdl">

  <start g="19,50,48,48">

  </start>

  <state name="guardedWait" g="98,46,127,52">

    <transition name="timeout" to="escalation" g="-43,-16">

  <state name="escalation" g="118,140,88,52" />

</process>


public void testTimerTransitionContinueBeforeTimerFires() {
    ProcessInstance processInstance = executionService.startProcessInstanceByKey("TimerTransition");
    
    String executionId = processInstance.findActiveExecutionIn("guardedWait").getId();

    // the next line will crash - duplicate row in the DB
    executionService.signalExecutionById(executionId, "selft");
    
    executionService.signalExecutionById(executionId, "go on");
    
    processInstance = executionService.findProcessInstanceById(processInstance.getId());
    
    assertTrue(processInstance.isActive("next step"));

    List<Job> jobs = managementService.createJobQuery()
      .processInstanceId(processInstance.getId())
      .list();
    
    assertEquals(new ArrayList<Job>(), new ArrayList<Job>(jobs));
  }
}
