[Seaside] updateRoot question

[Julian Fitzell]

If you're streaming the response, definitely not. If you're not, well maybe
technically, though I think even in that case the data has probably been
written to the response's data stream. You could certainly reset the
response but then you'd lose everything...

You could subclass the render loop code and... the render context class
maybe? Then you could hold onto the root in the context and not write it out
until you were done rendering content. Or something... you're getting in
deep at that point. :)
