FlashScope: anyone has a better name?
FlashScope is a feature of such frameworks like Tapestry or Stripes.
Behind the scenes, it uses session object and automatically retains
objects for the duration of this request and the subsequent request.
This scope object works best when redirect-after-post pattern is
utilized.
Struts has a rudimentary implementation of this tecnhique for handling
messages and errors. If a more generic FlashScope were created for
Struts, what do you call it:
* Drop scope -- this one sounds nice to me
* Autodiscard scope -- this explains that it is cleaned up automatically
* Roundtrip scope -- this explains what is it for
* Castaway scope
* Hold scope
* JettiScope (from "jettison", but may seem related to Jetty server)
* Just call it FlashScope like in Stripes
* Nah, FlashScope has Macromedia smell, should be something different,
like ____ (suggest yours)

Consider "click" scope, though it smells like a client point-of-view.

Yes, well it's "anemic" but I forgot to correct it! :-P

In fact I am thinking about a design pattern, but maybe no pattern at
all is needed (just because I am thinking about integration in Spring).
Notice that Scopes is still in 0.0.2 stage and I wanted only to present
my "idea", not the software itself.
Anyway, if you have more questions, please post them to the mailing
list, or mail me privately, I don't think that Struts people are so
happy with this off-topic questions.
Ciao

Antonio,
what is 'anhemic' programming? It's not in dictionary.com.
Your text on sourceforge says 'See "[put pattern name]" for reference;' but I
can't see the link. (is that some resource filter that didn't work during your
deploy?)

Great minds think alike. :) And no, I didn't even know about that project -
I guess certain needs are universal. Kudos on using the Apache 2.0
license.

Too bad Jackasses in the US Patent Office allow ideas this to be patented
when many people can come to the same conclusions as well as create them.

Why not call them custom scopes and link it into to contexts where
appropriate. That way you could name your scope and if it doesn't exist,
create it. Then you could have generic methods to handle all sorts of
scopes at once with generic methods like:
addScope("request").setAttribute(name, object);
addScope("session").setAttribute(name, object);
addScope("single").setAttribute(name, object);
addScope("someDialog").setAttribute(name, object);
Where a scope is created if the name doesn't already exist. Except that in
the "request" or "session" names, it automatically hooks into those scopes
for consistency. And for the Stripes equivalent "Flash" scope just call it
"single" scope or "next" scope. Basically that means you can name dialogs
of your choice plus have multiple ones. If they are linked to the Session
context then they'll auto-expire if left too long. Plus, we could add
something that enables scopes for a maximum number of requests (via a filter
perhaps) if that is a requirement, allowing a sort of auto-flush for these
potentially expired less-than-session scopes.
Regards,
David

FlashScope definitely smells of Macromedia.
Spring Webflow has several scopes in the virtual scope-scape between request
scope and session scope, called ConversationScope and FlowScope.
Perhaps they are more to your taste?

Umm, dialog is not really the same thing:
http://shale.apache.org/features-dialog-manager.html
"Conceptually, a dialog can be thought of as a set of labelled states,
connected by labelled transitions between those states."
I am talking about something like this but more generic:
/**

* under <code>Globals.MESSAGE_KEY</code> and
<code>Globals.ERROR_KEY</code>
* if the messages' <code>isAccessed</code> method returns true. This

* released here.</p>
*
* @param request The servlet request we are processing.
* @param response The servlet response we are creating.
*
* @since Struts 1.2
*/
protected void processCachedMessages(
HttpServletRequest request,
HttpServletResponse response) {
HttpSession session = request.getSession(false);
if (session == null) {
return;
}
// Remove messages as needed
ActionMessages messages =
(ActionMessages) session.getAttribute(Globals.MESSAGE_KEY);
if (messages != null) {
if (messages.isAccessed()) {
session.removeAttribute(Globals.MESSAGE_KEY);
}
}
// Remove error messages as needed
messages = (ActionMessages) session.getAttribute(Globals.ERROR_KEY);
if (messages != null) {
if (messages.isAccessed()) {
session.removeAttribute(Globals.ERROR_KEY);
}
}
}
Looking at the method's name, I might think of:
* Bean cache
* Cache scope

I agree with Paul (and Shale). Dialog, or even "Conversation", scope makes
the most sense. It's exactly as descript as it needs to be. If you can't
figure out what it means than you probably shouldn't venture out of page
scope.

How about ContinuationScope? Sounds decent to me since the second
request can be viewed as a continuation of the first.
Then again, if other frameworks are calling a similar facility
FlashScope, then there is some logic in using that name as well... that
way, when people compare frameworks, they can see that Struts isn't
lacking this as compared to other frameworks.
Incidentally, can you elaborate on how Struts supports this now? I'm
not sure I'm aware of this...

Shale calls this a dialog. I prefer that name. The reason is, obviously, is a continuous dialog across multiple requests.
