Signal Event Subscription is in suspended state after resuming process

Hi,I have Process A which I am suspending. As per business requirement when a particular condition is met, I need to resume the process and send a signal to it. This works fine if I have single process instance in suspended state. But if I have multiple process instances of same process in suspended

Hi Prachi.

I tried to reproduce your issue with jUnit test. Following test is based on activiti 5.15 sources and jUnit test.


  @Deployment(resources = "org/activiti/engine/test/api/runtime/ProcessInstanceSuspensionTest.testSignalEventReceivedAfterProcessInstanceSuspended.bpmn20.xml")
  public void testSignalEventReceivedAfterMultipleProcessInstancesSuspended() {

    final String signal = "Some Signal";

    // Test if process instance can be completed using the signal
    ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("signalSuspendedProcessInstance");
    runtimeService.startProcessInstanceByKey("signalSuspendedProcessInstance");
    runtimeService.signalEventReceived(signal);
    assertEquals(0, runtimeService.createProcessInstanceQuery().count());

    // Now test when suspending the process instance: the process instance shouldn't be continued
    processInstance = runtimeService.startProcessInstanceByKey("signalSuspendedProcessInstance");
    runtimeService.suspendProcessInstanceById(processInstance.getId());
    processInstance = runtimeService.startProcessInstanceByKey("signalSuspendedProcessInstance");
    runtimeService.suspendProcessInstanceById(processInstance.getId());
    runtimeService.signalEventReceived(signal);
    assertEquals(2, runtimeService.createProcessInstanceQuery().count());

    runtimeService.signalEventReceived(signal, new HashMap<String, Object>());
    assertEquals(2, runtimeService.createProcessInstanceQuery().count());

    // Activate and try again
    runtimeService.activateProcessInstanceById(processInstance.getId());
    runtimeService.signalEventReceived(signal);
    assertEquals(1, runtimeService.createProcessInstanceQuery().count());
  }

I started/suspended 2 process instances. They were not activated by signals. After that I activated one of them and sent a signal. Activated process instance was finished. Is seems that it works as you expected.

Regards
Martin
