i18n in Vaadin7: user is forced to log out if page is refreshed

Hello all,

from github (https://github.com/peholmst/vaadin-spring-webinar) i have found one example "i18n" which works. It can translate the text in two language.

Now i have integrated a login form with this example and met a problem:  after one login into the project, if he try to translate the text by click on corresponding button, he was forced to logout automatically.

Also when keyboard "F5" is pressed, one was forced to log out automatically.

What i expected is that, after one login into the project, the translation must work, if the corresponding button is clicked.

My project uses eventbus, spring and vaadin 7.  It can be found in github:  https://github.com/wantime/i18n

Your suggestion will be highly appreciated.

--------------  following are some code snippets ------------------

Code snippets 1: show login window

@Override
protected void init(VaadinRequest request)
{
    setLocale(request.getLocale());
    EventBusUserLogin.register(this);
    setContent(new LoginWindow());
}

Code snippets 2: jump to main view after login

@Subscribe
public void userLoginRequested(final EventUserLogin.UserLoginRequestedEvent event) {
     setContent(this.generateMainView());
}
