I don't know UIPainter. What worked for me to do user-interfaces for
the desktop and for the web is to use Magritte. The content management
system Pier primarily has got a web interface using Seaside, however
almost all functionality can also be used without additional code in
Morphic (the Squeak GUI framework).

Why do you make your life difficult with Comet? If you know the update
frequency in advance, then I see no point in using Comet. Have a look
at the class SUPeriodicalTest, why doesn't that work for you?

Aha, ok. I didn't know that you are on VW. Don't worry about the
message #scriptaculous, I only started with this refactoring recently
to avoid further pollution of the RenderingCanvas ... it is something
that comes in the future. There is no difference in the behavior.
