OK Here is my question. I am developing a "wizard" application, and I was
wondering if anyone has any ideas as to how to keep track of which step the
user is up to. I was planning on using a session variable and incrementing
it each time the page loads, but then when they hit refresh, it takes them
forward a step. Also, whats the best way to implement a "back" button?
should it just be a JavaScript call of History.back.....or maybe decrement
the step counter and have the servlet populate the form fields with the
stored values. If anyone would like to share any experience they have had
with writing such applications, or just know some cool tricks to use for
such a servlet, please reply.....every bit of info is a help.
Thanks,
