I am trying to get the active tasks of an instance using the below code. There is an active task at a process which is nested two levels from the parent process. And the below code is not capturing the active task that I am looking for. How can I get the tasks of a subprocess?

TaskSummary[] tss = (TaskSummary[]) pes.getCurrentTasksForProcess(
                                                  cddProcessId,
                                                  ProcessExecutionService.UNATTENDED_AND_ATTENDED_TASKS, 0,
                                                  Constants.COUNT_ALL, TaskSummary.SORT_BY_ASSIGNED_TIME,
                                                  Constants.SORT_ORDER_DESCENDING).getResults();

Hi karthikeyans75,

You should have a look at the Task Smart Service plugin. It has function that returns the active tasks for a process; you can pass the parent process id and a boolean parameter that determines whether the function should look at child processes. Here is the relevant code:

@Function
          public Long[] getActiveTaskIDsForProcess(ProcessExecutionService pes, @Parameter Long processID,
                              @Parameter(required = false) Boolean includeSubs) {
                    if (includeSubs == null) {
                              includeSubs = false;
                    }
                    Long[] idArray = new Long[0];
                    try {
                              ResultPage rp1 = pes.getTasksWithStatusForProcess(processID,
                                                  TaskSummary.TASK_STATUS_ASSIGNED, includeSubs, 0, Constants.COUNT_ALL,
                                                  TaskSummary.SORT_BY_ASSIGNED_TIME, Constants.SORT_ORDER_ASCENDING);
                              ResultPage rp2 = pes.getTasksWithStatusForProcess(processID,
                                                  TaskSummary.TASK_STATUS_ACCEPTED, includeSubs, 0, Constants.COUNT_ALL,
                                                  TaskSummary.SORT_BY_ASSIGNED_TIME, Constants.SORT_ORDER_ASCENDING);
                              idArray = new Long[rp1.getNumResults() + rp2.getNumResults()];
                              TaskSummary[] ts1 = (TaskSummary[]) rp1.getResults();
                              TaskSummary[] ts2 = (TaskSummary[]) rp2.getResults();

                              for (int i = 0; i < ts1.length; i++) {
                                        idArray[i] = ts1[i].getId();
                              }
                              for (int i = 0; i < ts2.length; i++) {
                                        idArray[i + ts1.length] = ts2[i].getId();
                              }
                    } catch (Exception e) {
                              LOG.error(e, e);
                    }
                    return idArray;
          }
