    fireUntilHalt with customworkhandler

    Hina Agarwal Newbie

      If we use cutom workitem handler as mentioned below and fireUntilhalt to invoke rules in reactive mode. While debugging, I found that before completing first task(line in blue & bold), it fires the rule which is active. After running of rule, it get back to end of completeworkitem.It creates a problem an thrpw an exception mentioned below.

       

      WorkItemHandler

      public class MyHumanChangingValuesSimulatorWorkItemHandler implements WorkItemHandler {
          private static int counter = 1;
          private WorkItemManager workItemManager;
          private long workItemId;
          private Map<String, Object> results;
          private Emergency currentEmergency;
      
          public void executeWorkItem(WorkItem workItem, WorkItemManager workItemManager) {
              this.workItemId = workItem.getId();
              this.workItemManager = workItemManager;
              currentEmergency = (Emergency) workItem.getParameter("emergency");
              currentEmergency.setRevision(currentEmergency.getRevision() + counter);
      
      
          }
      
          public void abortWorkItem(WorkItem workItem, WorkItemManager workItemManager) {
      
          }
      
          public void completeWorkItem() {
              results = new HashMap<String, Object>();
              results.put("emergency", currentEmergency);
              workItemManager.completeWorkItem(workItemId, results);
      
          }
      
      
      }

      Please suggest me can we use fireUntilHalt() with customhumantask handler. Why it always beahave differently?
