You might check out the Token component in Shale.

It is kind of similar to the synchronization token is Struts.

I can't think of an elegant way to do what you want, but here's an inelegant way:
Add logic to your application to add a counting parameter to the query
string of every URL (including those for form submission), so that
every URL looks something like this:
http://yourserver/foo.jsf?pageCount=24&x=2&y=5
The parameter would be incremented by a filter, which would store a
counter in the session and check the URL that's coming in. If the
URL's counter matches the count currently stored in the session when
the filter fires, everything's fine and the filter need only increment
the counter in the session so it can be used to create new URLs.
If the URL's counter doesn't match, you should be able to easily tell
what the user did to make that happen and take some action.
Obviously, making sure all URLs are thusly modified is a pain, but it's
the only way I can think of to do what you want to do, off the top of
my head.

Hi
I
have found a place where I could find if the user used the browser's
navigation buttons. The "getSerializedViewFromServletSession"
method of "JspStateManagerImpl" class knows the currentViewId and the
savedViewId, if they are different user must have pressed the back or
forward buttons of the browser. ( I am using myfaces 1.0.7).
But I still cannot tell if the user has pressed the back or forward
button. I need to perform some action if the user pressed the back
button. Is there any way to find that out ?
Any input is of great help, thanks in advance.
Srikanth

Thanks
for the information, do you know any more details, like at what point I
can trap the back button event using the state manager? Is there a
request generated when the back button is pressed ?
Thanks

I haven't done this yet, but I believe you'd handle back button issues
with a custom StateManager.:
