title: How can I make Two JSF components communicate using Listener and Event
body: <p>I have two jsf <strong>custom-components</strong> which are supposed to communicate. 
  These components are a DataTable and a pager.
  I am looking for that when changing the model of the DataTable, an event triggers to allow the pager to be updated, and vice versa. and that maintaining their independence. is it possible to do so using the listener and the event?</p>
