Subject Re: Ajax lifecircle integration

We should also take a look at what Craig has come up with for Shale. 
I'm not sure whether he as any code (haven't looked yet) down but I
know he has been giving a lot of thought to hwo to incorporate Ajax
into JSF.

This is a good reason to keep any Ajax components in the sandbox for a
while until we get this sorted out.  It will be easier on our users to
come up with something really good and get all of the kinks worked out
before they start relying on our approach.

I am still thinking the processAjax() method or whatever would be a
good idea.  I'll need to re-read some of the posts from several months
ago concerning this topic because there seem to be a lot of good ideas
on the subject.
