public TopBar(String id, Model model,CmsFacade facade) {
super(id, model);
MyApplication app = (MyApplication)
RequestCycle.get().getApplication();
app.getFacade();
app.getFacade().getSomeBS();//it will cause error
==========================================================================================

public class MyApplication extends WebApplication {
private CmsFacade facade;
public CmsFacade getFacade() {
