I'm not entirely sure I complete understand what
you're asking for.
The *most* common solution for this is a
post-redirect(-get) where the form is posted,
processed, and you redirect to the list.
Messages for that are generally stored in a
"flash"-like context (session but with automagic
removal after the next request completes).
that' Interesting. Where can I read about flash-like context you are
talking about?
If your list action isn't ParameterAware it won't get
any params anyway, I believe.
Sure, but what if I still want it to be able to get some parameters
other than from redirect
(I don't want to limit this action in any way)
(it kills the valuestack object in the request
map as far as I have seen while debugging, which for
some obscure reason prevents the final JSP to obtain
any of the properties of ListAction)
Some "obscure reason?" The value stack is where the
properties of the list action are *kept*. Of course if
you remove it the properties will be gone.
The funny thing is that cleaning request map in the first action totally
breaks the second action.
if you have a getter in the second action it simply returns nothing when
accessed through OGNL from JSP. That's weird.
If you want to forward, the "best" way to do it is
with an action-chain. If you want to redirect then you
need to have some way of storing the message, like you
said.
As I said, if using chain, the whole load of parameters is applied to
the second action, which I want to avoid, I want it to get nothing
except of what I'm explicitly define.
That's just the nature of HTTP, AFAICT. You can work
*around* the limitations of HTTP with interceptors,
parameter map tweaking, etc. but you can't *avoid*
those limitations.
Someone else might be more helpful, though.
