[GrooveApp-devel] Another GrooveApp idea for comment

[Marcus B. <mb...@gm...>]

So, here's another silly idea that I'd like to throw out (in case
you're interested).

So, it might behoove a new Java framework to work out of the box with
Ajax.  Well, as you guys now have seen, there really isn't a good way
to get data from the server to the client for Ajax calls in Java w/o
using the SessionContext.

Well, since in GrooveApp, the framework controls the requests, perhaps
it would be a good idea to include an Ajax{Request}Context (or
GrooveRequestContext).  This way, the dev could put an object of
interest in that context, and asynchronously call methods to update
that object.  It wouldn't be too hard to do, as you'd just have to
create a new context (if needed), give it an id, and populate it.=20
Then with the next request, you could scan the parameter list for
AJAX_CONTEXT_ID (or something like that), and load the appropriate
context.  The ajax call from the client would just have to include
AJAX_CONTEXT_ID in as a parameter in it's call.

The Ajax{request}Contexts could be stored as a map in the
SessionContext.  When a new request comes in, the last AjaxContext
could be cleared (or set to timeout in 2 minutes, or something).

Ideas?
