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 response going

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<mailto:struts-user-unsubscribe@;jakarta.apache.org>
"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.
