[jsr-314-open] Autoupdate / always render

So, I got a chance to discover more about RichFaces today, attending a tutorial by Max Katz. 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? Jim P.S. Filed bug 629 on this topic.
