Enclose your buttons in an <h:form> tag.

Subject: [newbie]: click on commandButton does nothing. Why?
I am sure this is a super simple newbie problem, but would you mind
helping me? Thanks so much!
I wanted to start playing with MyFaces and JSF by building a tiny
application:
index.jsp simply forwards to menu.faces (which is the file menu.jsp) In
menu.jsp there is one little button leading to details.jsp In
details.jsp there are two buttons: one leading back to menu.jsp and one
leading to content.jsp content.jsp has a button to menu.jsp.
I can deploy everything in Tomcat 5.5 and call each page individually by
using the .faces suffix instead of their real file name suffix .jsp.
But here is the thing: when I click on any of those buttons, nothing
happens. Absolutely nothing. I have added a System.out... statement in
the method that is supposed to be called but that is not called either.
Do you have any idea what I did wrong?
Here some code:
