Hi everybody,
I have a problem with cookie stored locales, switched by the user with
T5.3.6. The code snippets are below, commented.
Tapestry loads the LocaleRequestFilter and invokes the service method on
each request. I get the correct language value out of the cookie. The
problem is, that this value isn't stored correctly (as I assume). The
line is
"localizationSetter.setLocaleFromLocaleName(preferredLanguage.toString());".
During the page and component rendering, Tapestry uses always the
English l10n. The default is German (TestComponent.properties => de,
TestComponent_en.properties => en).
Does anyone know where the problem could be?
Any help is appreciated :-)

I've tried the following:
AppModule.java:
public static void
contributeApplicationDefaults(MappedConfiguration<String, Object>
configuration) {
configuration.add(SymbolConstants.ENCODE_LOCALE_INTO_PATH,
false);[...] // I don't want the language code in the address => to cookie
configuration.add(SymbolConstants.SUPPORTED_LOCALES, "de,en");
}
public static void bind(ServiceBinder binder) {
binder.bind(TimingFilter.class).withId("TimingFilter");
binder.bind(LocaleRequestFilter.class).withId("LocaleRequestFilter");[...]
}
public void contributeRequestHandler(
OrderedConfiguration<RequestFilter> configuration,
final Logger logger,
final RequestGlobals requestGlobals,
final Cookies cookies,
final LocalizationSetter localizationSetter,
@InjectService("TimingFilter") RequestFilter timingFilter,
@InjectService("LocaleRequestFilter") RequestFilter
localeRequestFilter) {
configuration.add("TimingFilter", new TimingFilter(logger));
configuration.add("LocaleRequestFilter", new
LocaleRequestFilter(requestGlobals, cookies, localizationSetter),
"after:*");
// This is the RequestFilter for the locales.
}
In the ...webapp.services.LocaleRequestFilter.java:
public class LocaleRequestFilter implements RequestFilter {
private RequestGlobals requestGlobals;
private Cookies cookies;
private LocalizationSetter localizationSetter;
public LocaleRequestFilter(RequestGlobals requestGlobals, Cookies
cookies, LocalizationSetter localizationSetter) {
this.requestGlobals = requestGlobals;
this.cookies = cookies;
this.localizationSetter = localizationSetter;
}
@Override
public boolean service(Request request, Response response,
RequestHandler handler) throws IOException {
TranslatedLanguage preferredLanguage = null; // is an enum
// Here comes some code to read the HTTP header and the cookie
to decide, what to do.
// This method is invoked and reads _the_correct_ cookie value.
System.out.println("set language : " +
preferredLanguage.toString());
localizationSetter.setLocaleFromLocaleName(preferredLanguage.toString());
// Here could be the problem, because the preferred value isn't
stored.
return handler.service(request, response);
}
}
In the component, where I change the cookie value:
private void onActionFromLanguageMenu() {
cookies.writeCookieValue(PlainTraySetting.COOKIE_LANGUAGE_VALUE_NAME,
selectedLanguage.toString());
// I just write the selected language to the cookie. That works
perfectly.
}
