Can the isTokenValid and saveToken be in the same Action ?

I'm trying to use the saveToken function but is not working here is
what I have: a parameter called "action"
if("save".equals(request.getParameter("action")))
{
if(!isTokenValid(request)){
System.out.println("our of transaction order");
resetToken(request);
}
//save stuff
}
else if("validate".equals(request.getParameter("action")))
{
saveToken(request); //validate stuff
}
any inside will be very helpful
thanks

No-cache settings in the controller will make sure that every

Through the controller will have its head setting to no-cache on the

as the user
Going to another page, and so when the user click the back button the
browser
Will request to the server for the new contents of whatever on the
history Stack. With transaction token, if there is a match meaning
you have a good
Transaction, a sync with the current state, and you can go on and
process
The request. Else, there isn't a match with the token which mean out of
sync
Then you can handle the condition as if it is out of sync.
Hope this would help.

That is an absolutely hideous solution to the problem. Breaking the
user's
back button will only make them angry.

You can disable the back button by using JavaScript history.forward()
at
the
top of your page. But i dont know if that solves your problem.

Subject: back button
I have a JSP that has a sequence of actions. First one is
"validate" which will validate some IO File and the next one is
"load" to load the file.
When the user hits "validate" it sends a request to the back-end to
do some validation and I get back a response. When I hit Load it
sends a request to the back-end to persist that file.
the Load button depends on the validation button. When click
validate and get an ok response, load shows.
The problem is the back button on the browser, the file is already
validated but if I hit the back button the ui and the back-end are
our of sync I can validate again.
Any one run into this problem? how can it be handlel? thanks.
