[Seaside] changing components without a complete redraw

[David Pollak]

Howdy,

I'm trying to figure out how to use Seaside and Scriptaculous to  
cause components on a page to be redrawn if they have changed from  
the last HTTP request.  The scenario looks something like:

html anchor
          onClick: (html updater
          callback: [ :render | self changeMe. self otherComponent  
changeYou. render renderAllChangedElements ]);
          with: 'Do Change'.

The existing implementation of SUUpdater does not collect the changed  
components and push all the changes back to the client at once.  Has  
anyone done any work to collect all the changes and push them back to  
the browser (the renderAllChangedElements call)?  If not, I'll be  
happy to knock something together.

Thanks,

David
