A few years ago, when Struts was not still available, we programmed a web layer framework much more primitive than Struts but with similar functionality for the project I was involved. One of the functionalities we had was request flow control, so we were sure that the user wasn't going back and forth and we had the right information in the session. Whenever there was a request that was not proper following the current flow, a message error was showed to the user, with the suggestion to begin the flow again.
We didn't reach that far, but I think such a functionality may provide a way to define "wizards" or page flows and let the application have a callback method to clean the session stored in data in case the user leaves the wizard. This is a functionality that I'd love to have in Struts. Right now, I try to clean the session when I reach the final step of such a series of pages, but you are not guaranteed that the user ever reaches it.
The other solution is having all the data introduced so far by the user in hidden fields (though I don't recommend it).

AFAIK, why not put form bean in hashtable under well known name in application scope - last resort, cause as you mentioned request not applicable, session not available.... you are in full charge of form bean. populate that bean in application scope as you like from newly created form bean or replace it all at once. Have to e.g. prepend key with user information(getSessionID()) to get same bean for user back?

How do you prevent the session from filling up with junk from previous screens? Or to put it another way:
I have written some screens that have to store the form bean in the session scope as each screen is interconnected and uses the same instance of the form bean. If I change the scope to request a new form
bean is created for each screen (every time a jsp file is rendered). Is
there a way of implementing multiple screens with the same form bean with a request scope?
