can i change locale manually or not ???

[Mohammad Shamsi]

i was read in tapestry localization guide that : Tapestry does not yet
support changing the locale, but that will be available shortly.

but in wiki T5 Howto, i read a guide to changing locale  in tapestry, look
at code :

@Inject
private PersistentLocale persistentLocale;

public void onActionFromChangeLocale(String language)
{
        persistentLocale.set(new Locale(language));
}


but change locale here, don't effect on my pages :( , any idea ?
