Don't think of it as "returning" to the "first" page but as moving forward to
the control page.
A simple approach is to use a dynamic element such as a request attribute to
hold the message or a state variable to drive retrieval of the message. Use
EL, JSTL or JSF idioms to control whether the message is displayed.
I am still learning JSF, so undoubtedly I'm ignoring some JSF component that
manages messages such as these.
