I've used Announcements and prefer them for inter component event
handling.
we've been using Announcements in our Seaside App for years now and
apart from beginners' problems (like not unregistering properly and
therefor having all kinds of strange phenomena) they serve their
purpose very well. The housekeeping of subscriptions is key, you can
shoot yourself in the foot easily.
It's been five years since I used them in Seaside. Have they
held up well?
Are they local to a session?
No. They are local to the Announcer that you use. We use our
WASession subclass. But Seaside does nothing to make Announcements
local to anything. Whoever subscribes to the Announcer gets
Announcements. So to some extent you can make them local to a
Session by using the Session as the Announcer, but still you could
forcibly register subscribers that are outside of the Session. It is
your responsibility.
Does jQuery Ajax introduce issues?
Not that I know of. But that doesn't necessarily mean anything ;-)
