Hi all,
I am trying to implement a call stack with stripes so that I can return
the user to the page he came from, e.g. after processing a POST.
For example, I have a page "Formpage1" which is accessible from some
other pages and contains a form with some input fields. Now, the user is
on some other page "Otherpage123" and clicks a link that takes him to
"Formpage1". What I want to do is that after the user clicks the submit
button on "Formpage1" I want to handle the POST request as usual and
then redirect him back to where he came from ("Otherpage123", in this case).
Now, where I'm stuck atm:
I am storing the pages in a java.util.Stack that is stored in the
FlashScope. The problem here is that when I'm forwarding to a JSP the
FlashScope is lost (I'm using the Preaction Pattern).
If I stored the Stack in the Session directly, I would need to copy most
of the FlashScope functionality, especially adding a parameter that
identifies each window (when the user has several tabs open with the
application) and removing stale Stacks after some timeout, which I'd
like to avoid.
Maybe someone has a better idea how to implement this or can help me
with these problems? Thanks!
