Is there any
standard way for dealing with messages that are passed between an action and a
redirect result? As I understand it, once a redirect is done, a new request is
created and any messages you may have stored in an action (via actionErrors or
something hanging off of the action itself) are gone.
The scenario I'm
trying to deal with is an administrative password reset function. It
autogenerates a password, then does a redirect back to the user detail page. I
want a message to say what the new password is. It works if I do it as a
chaining result, but that has a problem. On a chain action, after a successful
change, the URL is still pointing to the reset action. If the user hits
"refresh", instead of getting a refreshed view page, they'll end up calling the
action again. For something like this, that could cause problems. I usually do a
redirect after add and save actions without any problem, because I usually never
need to display a message. But in this case, if I don't display a message, the
user won't know what the password was reset to! Note that this is only one
example, but I can think of a ton of other things that a similar pattern would
help address.
I think Struts
maintained some sort of information on the session, and that may be the only way
to handle this, but I wanted to see what others had
experienced.
Thanks,
