I don't know the context/history... but want to voice some reservation
regarding this "feature".
I hope we have a way of skipping this for cases such as:
1) If my Ajax response is not going to be handled by JSF2's standard
JS. This is obvious... but I thought I'd state it anyway.
2) If I am making several Ajax requests in a short amount of time (i.e.
immediately after the page is loaded), I would obviously not want to
re-render all the auto-update components several times.
3) If I require a fast, light-weight request (i.e. auto-complete text box).
"Auto-update" seems like a great "push" feature, or polling feature
that
is separate from other Ajax requests. If I understand it correctly,
having an "always render" component seems a little excessive.
Thanks!

Autoupdate can also be thought of as "always render" - it's the
process of marking out certain id's to always be rendered on any ajax
request.
I can now say that, no, we don't support autoupdate functionality -
while a page author doesn't really need this functionality, it's
possible to imagine a use case for it as a component library author -
and in that case, while there's hacky things you can do to almost get
there, it won't really be possible with the existing APIs.
Since in an earlier message, I said that I wasn't aware of anything in
particular that couldn't be done with the API, well, here's one use case.
Adding such an API would be pretty easy:
void jsf.ajax.addAlwaysRender(String id)
I'll file a spec RFE for this (there seems to not be one!), but I was
wondering:
What's the context/history behind this not being included in JSF 2.0?
Can anyone elaborate?
