next is my code:

@EventHandler("parttime_count_tempNext.onClick")
public void doNext(Event event) {


s.setSessionList("partime_count_temp", parttime_count_tempModel.getListmodel());
parttime_count_tempWin.getChildren().clear();
Executions.createComponents("work/billable/garbage_count_temp.zul",parttime_count_tempWin, null); }

since the page was designed for standalone, you should not use createComponent to include another zeta page.
try Executions.sendRedirect(uri)
