Thanks for your reply. doNothing() actually returns false.
I checked the wiki website, and it looks like commanLink calls submit() no
matter what and I cannot change its behavior. And outputLink go to the
place defined in value anyway. So, I may try with commandButton instead
adding type="button" (or just use f:varbatim).

JSF generates a block of Javascript and it is tied to the onclick
event. Disregarding the details, it basically calls submit() which post
the form to the server
