Tuomo,
Not totally finalised but at the moment I do it a bit
like the example below.
If you searched the archives for 'logon page' there
are ways you can forward to the logon page & have it
return to the page that started it, which is the same
thing. These example are probably better than mine!
Keith.
======
example - form1 transfers to form2 & wants form2 to
transfer to form1.
form1 has
/*
* Let next form know where to return to.
*/
request.addAttribute("returnTo",
"globalForwardForm1");
form2 has
/*----
1 - save the input returnTo value. 1st time in caller
has stored it as req. attribute. Subsequent times this
action has saved it as a hidden field on the form
(could save in the session).
------*/
String returnTo = request.getParameter("returnTo");
if (returnTo == null) formBean.getReturnTo();
thisForm.setReturnTo() = returnTo;
/*
* 2 - on completion
*/
return new ActionForward("returnTo");
