1. Problem

- Working with OpenSocial message bundle for localization, sometimes it's necessary to bind dynamic arguments to the message. For example, we have greeting message like this: Hello {user} in which user will be replaced by user's name. But currently with OpenSocial api, we can't. We just can get message bundle by the key without passing any arguments for substitution.

- So this is my approach: using eXo.social.Locale.getMsg(key) the same as prefs.getMsg(key) and eXo.social.Locale.getMsg(key, [val1, val2,...]); for dynamic arguments binding with message bundle.
