I auto-generated process and task forms and I receive the error below.  The problem seems to be I try to lookup an activity by the task id and there is no activity but the call to resolveById returns a list containing a null object.  Why does the code expect to find an activity for my random task? 

   public void renderFormViaPlaceManager(@Observes RenderFormEvent event){

        String taskName = event.getParams().get("TaskName");

        if(taskName == null || taskName.equals("")){

            return;

        }

        DefaultPlaceRequest defaultPlaceRequest = new DefaultPlaceRequest(taskName, event.getParams());

        Set<Activity> activities = activityManager.getActivities(defaultPlaceRequest);

        if(activities.isEmpty()){

            return;

        }

        AbstractWorkbenchScreenActivity activity = ((AbstractWorkbenchScreenActivity) activities.iterator().next());

        IsWidget widget = activity.getWidget();

        activity.launch(place, null);

        activity.onStartup(defaultPlaceRequest);

        view.getFormView().clear();

        view.getFormView().add(widget);

        activity.onOpen();

        view.getFormView().setVisible(true);

        view.getFormRenderer().setVisible(false);

        loadForm = false;

        initTaskForm("");

    }  

  private Collection<IOCBeanDef<Activity>> resolveById( final String identifier ) {

        if ( identifier == null ) {

            return emptyList();

        }

        return new ArrayList<IOCBeanDef<Activity>>( 1 ) {{

            add( activityBeansCache.getActivity( identifier ) );

        }};

    }
