Re: [Springframework-developer] SWF - Creating HTTP sessions - Feedback needed

Not sure why this didn't come through...size?  I see it and another
post from Rob in the archive...just never got them (checked another
developer too).  If this is a duplicate for some, I apologize.

What about an implementation that would 'do what is best'.  Save to
the session if it already exists, serialize to the request if not.
Then have a custom tag to spit out the flow info in the form.  The tag
would pull the serialized flow info from the request (if it exists)
and add a new hidden input field for it (_flowInstance or
something)...otherwise if a session exists and the info is on the
session it would spit out what is expected now (the _* hidden fields).
At the beginning of a request, it would look to see if the serialized
param (_flowInstance) is on the request first...if so, deserialize.
If not, see if a session exists and pull from the session using _*
params.

If you have a truly complex object graph, set a 'requiresSession'
boolean to true (defaults to false)...although I would think it best
to try and keep it as simple as possible when going in the session.

With this approach your not doing more than you need (when a session
does exist), and (as a bonus) you can have flows that are used by
non-session visitors and with-session users, and the impl would 'do
what is best' in both situations.
