Live updates from Facebook with spring-social.io

I don't like posting a general question like this, but I couldn't find any example on this topic in the spring-social.io site ( here and here ), and neither (here)

Given the description of the site ... it should be possible (retrieved)

Functions

A service provider and connection factory for use with Spring Social connection framework.
An API binding for Facebook Graph API.
**A real-time update controller for handling real-time update callbacks from Facebook.**
A disconnect controller to handle disconnect callbacks from Facebook.
Much more.

      

        
        
        
      

    

So has anyone tried to do a live update subscription using spring-socials.io? If so, then any information on how to do this would be much appreciated.

Thanks, Alejandro
