How to keep current language when invalide session in wicket

My application is supporting more then language. Problem is when user logout (which means I call getSession().invalidate()) then current language is lost and there is created new session with default language.

Language is sets via link:

add(new Link<Void>("goSk") {

    private static final long serialVersionUID = 1L;

    @Override
    public void onClick() {
        getSession().setLocale(new Locale("sk", "SK"));
    }
});

add(new Link<Void>("goEn") {

    private static final long serialVersionUID = 1L;

    @Override
    public void onClick() {
        getSession().setLocale(Locale.US);
    }
});

So question is how should I keep current language when I invaliate session

EDIT: invalidating session does not allow to reset a parameter in the session. a viable solution I successfully tested is to use PageParameters

Locale currentLocale=getSession().getLocale();
session.invalidate();//clear all session data
PageParameters pp=new PageParameters();
pp.add("locale", currentLocale.getLanguage());
setResponsePage(<you class>.class,pp);

and in the page you specified in setResponsePage you have to provide a constructor with PageParameters something like

 public class Login extends BasePage {
    public Login(PageParameters pp) {
        //your code here
        logger.debug("login user"+pp.getString("locale"));
    }

Wicket passes the parameter via query string I tried this with a working test case

Better use a Cookie for anonymous users. Before invalidating save the lang in a cookie. In YourSession#getLocale() use the cookie if there is no user.
