Thank you kevin, this seems to makes the most sense to me. and will try and implement this.

Although there are many ways to solve this problem, I
think this is probably the cleanest and simplest.

Create one ActionForm to hold all of the data, and
session scope it.

Create an Action to handle the final submission after
the user completes the 4 pages. This action should
make the calls into your business logic do the work of
processing the completed form. Call this something
like XXXXProcessorAction.

Create another Action to handle moving the user from
page to page within the 4 pages. This action should
have intelligence to know the ordering of the pages,
but need not know how to handle a completed form. If
this action detects that the user has clicked "next"
after the 4th page, it should forward to the other
action to complete the work. Call this something like
XXXXNavigatorAction.

All of the navigation buttons would submit to the
XXXXNavigatorAction.

This design give you the flexibility to implement both
a 4 page wizard, and a 1 page expert screen (that
submits directly to XXXXProcessorAction), with no
duplicated code. This design also gives the user the
freedom to use either your "Next" and "Back" buttons,
or the ones on the browser.


Good luck!!

P.S. The only trickery you'll need will be intelligent
validation that only checks the 1/4 of the form the
user completes per page. You should also remove the
form from the session after the user completes (or
cancels) the 4 pages.
