Create sample data when user signup

[antonini]

Well, I'm trying to to create sample data when the user signup.
I did it on the method save(Identity) of the UserService but the problem is that on this method I don't have the user language, context or even the request to translate the sample data.

How can I get the user language? I've used the code below but it always bring my machine language (Locale.getDefault()):

    if (play.mvc.Http.Context.current.get() != null) {
        lang = play.mvc.Http.Context.current().lang();
        logger.debug("Has a Context!!" + lang);
    } else {
        logger.debug("No Context!! :(");
        Locale defaultLocale = Locale.getDefault();
        lang = new Lang(defaultLocale.getLanguage(), defaultLocale.getCountry());
    }

Is there a correct / better place to do that? Can I access the user language on that place?
