Problem with getWindow and server restart

General
1

Hi,

I implemented getWindow to handle parameters given to my application. So far it seems to work. The only problem is the following case:

  1. start server
  2. load page http://localhost:8080/ui/VAADIN/t23442?sessId=1238888
  3. stop server
  4. refresh page => window-name is 1 instead of t23442
  5. Clear browser cache
  6. refresh → everything is working as expected

How can I handle a server restart without forcing the user to clean the browser cache ?

Regards
Roger

        if (super.getWindow(name) == null) {
            final TouchKitWindow mainWindow = new TouchKitWindow();
            mainWindow.setCaption(getCaption() + "/" + name);
            mainWindow.setName(name);
            mainWindow.setWebAppCapable(true);
            mainWindow.setPersistentSessionCookie(true);
            setMainWindow(mainWindow);
            mainWindow.addParameterHandler(new ParameterHandler() {
                @Override
                public void handleParameters(Map<String, String[]> parameters) {
                     // @formatter:off
		     mainWindow.setContent(createMainComponent(
							new WindowName(name),
							new ParameterMap(parameters)));
		    // @formatter:on
                }
            });
        }
        TouchKitWindow mainWindow = super.getWindow(name);
        if (mainWindow.getContent() instanceof UINavigationManager) {
            if (!mainWindow.getName().equals(previousName)) {
                UINavigationManager uiNavigationManager = (UINavigationManager) mainWindow.getContent();
                uiNavigationManager.refreshData(new WindowName(name));
            }
        }
        previousName = name;
        return mainWindow;
    }
