Hi everybody, I know that what I try to explain is a bit difficult to
understand without know all the context but I try to do it the same:).
I have a datatable that contains a list of student. In another page I
insert a new student. When I click on "save" button I save the new
student and I return to the page with the datatable. The problem is:
when I add a student I must notify the user that the student is added
correctly with a message in the 1st page like "The student is added
correctly". This message must display only after I added the student
not when I see for the first time the page with the datatable. How can
i do this? Thanks to all.

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.
