Hi,
I am trying to implement a simple Back mechanism which uses Back buttons in
the page (encouraging users to use this rather than browser Back which is
not a good idea). Lets call the pages Page1 and Page2. A Page 1 action
brings user to Page 2. Page 2 has a Back button. The basic mechanism is
trivial, ie. an action handler for Page 2 Back which forwards to Page1.
However the problem is I want to be able to go Back to pages other than
Page1 since the user can also get to Page 2 via Page3. ie. I want to be able
to do
Page1->Page2->(back)->Page1
Page1->Page3->Page2->(back)->Page3
Is there some way to control the forwarding for the Page2 Back handling and
know which page to go back to ? The 'static' mappings I would set up in
struts-config.xml appear to only allow me to configure navigation back to
one specific page. I was considering implementing a 'page stack' object and
passing it as a session attribute but I would have hoped that the Struts
framework would make this possible in some easy way.
I suppose some of the wizard ideas might help but a wizard is essentially
different from what I cam trying to achieve in the sense that Back in a
wizard always go back to a specific page.
Any help would be greatly appreciated.
