I found this thread as a solution to my problem of switching locale. I can switch locale just fine and setting PersistentLocale works until I strip the URL from language code. Juan's example below is exactly what I need, however, because I'm returning to Tapestry after two years of inactivity, I don't understand how I can access session from custom request filter he suggested. Do I add session as parameter to the method? If so, how do I retrieve language I've set in my Layout component?
More specifically, what happens in my case is this: user switches locale using a language dropdown (provided in my Layout component), then language is saved: @Persist private String language; So my language is in session, but how do I access it from request filter? I have a getLanguage in my Layout component, that's all.

It would be something like this: public class LocaleComponentRenderRequestFilter implements ComponentRequestFilter { private final SecurityContext securityContext; private final PersistentLocale persistentLocale; private final LocalizationSetter localizationSetter; private final Logger logger; /** * @param securityContext * @param persistentLocale * @param logger * @author jmayaalv */ public LocaleComponentRenderRequestFilter(SecurityContext securityContext, PersistentLocale persistentLocale, LocalizationSetter localizationSetter, Logger logger) { super(); this.securityContext = securityContext; this.persistentLocale = persistentLocale; this.localizationSetter = localizationSetter; this.logger = logger; } /** * Changes the locale * @author jmayaalv */ private void changeLocale() { if (this.securityContext.isLoggedIn() && this.persistentLocale.get() == null) { String language = GET LANGUANTE HERE FROM A COOKIE, SESSION OR WHATEVER if (StringUtils.isNotBlank(language) && !"en".equalsIgnoreCase(language)) { if (logger.isDebugEnabled()) { logger.debug("Changing user locale to '{}'", user.getLanguage()); } this.localizationSetter.setLocaleFromLocaleName(language); } } } @Override public void handleComponentEvent(ComponentEventRequestParameters parameters, ComponentRequestHandler handler) throws IOException { changeLocale(); handler.handleComponentEvent(parameters); } @Override public void handlePageRender(PageRenderRequestParameters parameters, ComponentRequestHandler handler) throws IOException { changeLocale(); handler.handlePageRender(parameters); } } After this u just need to contribute the chain in ur module: public static void contributeComponentRequestHandler(OrderedConfiguration<ComponentRequestFilter> configuration, @InjectService("LocaleComponentRenderRequestFilter") ComponentRequestFilter localeFilter) { configuration.add("LocaleFilter", localeFilter); --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
