Vaadin 7: Server Push has conflict with Spring i18n

Hello everyone,

i have used the "i18n" example from github to translate the text and it works. In this example the listener "org.springframework.web.context.ContextLoaderListener" has been used.

now i would like to use "server push" on the project. As Push annotation is used, i can update the UI through thread. But the translation doesn't work anymore. I even didn't get any error message.

the evironment is following: JDK8, Tomcat8, Vaadin7.5.5, Spring4.2.1.RELEASE, Maven3

In Method service(..) in @WebServlet class, the value of "localeResolver.resolveLocale(request)
" was still the old locale, when the locale has been changed on UI.
This value should be changed to the current locale but it didn't.

@Override protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    final Locale locale = localeResolver.resolveLocale(request);
    LocaleContextHolder.setLocale(locale);
    ServletRequestAttributes requestAttributes = new ServletRequestAttributes(request);
    RequestContextHolder.setRequestAttributes(requestAttributes);
    try {
        super.service(new HttpServletRequestWrapper(request) {
               @Override public Locale getLocale() { return locale; }
        }, response); }
    finally {
        if (!locale.equals(LocaleContextHolder.getLocale())) {
             localeResolver.setLocale(request, response, LocaleContextHolder.getLocale());
        }
        LocaleContextHolder.resetLocaleContext();
        RequestContextHolder.resetRequestAttributes(); }
    }

any suggestion would be appreciate. Thanks.

Does it work if you use long polling, which is based on HTTP (as opposed to websockets, which is the default)?

@Push(transport = Transport.LONG_POLLING)

Amazing, it works! Thanks.
