What I have for the foundation of our Struts app:
-----------
SmoAction
+-void setSource(SmoActionMapping, HttpServletRequest, String key)
+-ActionForward getSource(SmoActionMapping, String key)
SmoActionMapping
+-String getSource()
-----------
Step 1: Setting the Source
On SmoAction, I lazy load a Map into the user's session if:
+-Request has a "source" parameter
+-else SmoActionMapping.getSource() != null
Then I use the passed String "key" to set the String "value" from either the
request or the mapping. End Method.
-----------
Step 2: Getting the Source
On SmoAction, I call getSource() with the SmoActionMapping for reference and
the String "key" for lookup. The reason for not storing the ActionForward
itself is that I would rather have the ActionForward relative to the current
Action being executed, instead of the one that originally set the source
(this is debatable, but it meets our needs).
+- If there is a map in the session to look against
+- use the passed key to find a forward name
+- if not null, then use the passed ActionMapping to findForward
-----------
Notes:
Variations on this could include allowing a stack to be created for each
key. So when I call getSource() I get the last value that was set for that
key.
Some of the issues we ran into were storing parameters and resubmitting
forms. Because we use SessionBeans to preserve state on our crutial areas,
re-requesting an Action would be able to restore the view based on a session
bean and not on parameters.

Care to elaborate? Do you have a Map of String-String name/value pairs,
or are you putting ActionForwards in the Map? What do you mean by
'allow the actionmappings/request specify a source'?
I'm not happy with the way I'm doing the and am looking for something
better. However I tend to get lost in the details and can't step back
and design the whole solution.
