怎样取得下一环节执行者？

julio

lFlowTask := command.FlowTasks.GetFlowTask(FlowBroker.FlowControl.CurrentProcUnit.SuccedentUnits[0]);  //下一环节任务
执行者DepID：lFlowTask.Executors.Items.DeptID //变量i指第i个执行者
执行者PositionID ：lFlowTask.Executors.Items.PositionID
执行者PersonID lFlowTask.Executors.Items.PersonID

for i:=0 to Command.FlowTasks.Count-1 do
  begin
    lFlowTask := Command.FlowTasks as TFlowTask;
    s := lFlowTask.Subject;
    for j:=0 to lFlowTask.Executors.Count-1 do
    begin
      lOrgURL := lFlowTask.Executors[j] as Org.TOrgURL;
      s := s+#13#10+lOrgURL.DeptID+'|'+lOrgURL.PositionID+'|'+lOrgURL.PersonID;
    end;
    Dialogs.ShowMessage(s);
  end;
