Brian,
I had the same problem. I did the following:
1) save the errors in the session instead of the request
2) wrote a method that takes the messages from the session, and puts it
into the request. I call that after my redirect is done.
I thought about having the .jsp pull it out of the session and display
it, but I was concerned about that being fragile if the user's control
flow somehow didn't lead to the message display page. So instead, I do
it in my controller (we're using tiles, too, so I have more than 1
action being called for every page).
I'd be interested in hearing what approach you took to solving this
problem.
cheers,

Has anyone else run into this scenario before? I've searched the archives
and couldn't find much on the topic of errors and redirect.
During an action, I want may encounter an error condition and I want to
REDIRECT the user back to the page where they came from and pass along the
error. I need to do a redirect to get the URL of the browser to reflect
the page where they came from (in case they bookmark the link). If I
don't do a redirect then the page being displayed reflects the action they
were trying to perform and they are out of synch.
The problem with this is that I can't pass the ActionErrors /
ActionMessages on the request as they are lost with the redirect.
One option I've thought of is to put the data on the session and then
strip it off in the jsp--each request in a session would need to put data
in via a unique key that's not in the session (in the event of
simultaneous requests).
