It is Safari, another unsupported browser.
I don't like hacks that are likely to break with the next service pack.

Just an idea. It might not work for you.

I don't want a DIV around all my components.

I don't see how these DIVs could be valuable for a designer, as they
are probably auto generated. What worried me initially was that I had
the impression that you wanted to put a DIV around every component.

That makes sense.

Sure that's a detail. I don't see any problems in starting with a
subclass of WAComonent, I just feel that maybe later on you might want
to choose a different superclass. WAComponent provides a lot of
functionality that might not be too useful in your context.

So far, I don't see any use of continuations. Seaside only uses
continuations to wait in the middle of a method for the next request,
e.g. with #call: and #answer:. The state backtracking has nothing to
do with continuations (with the exception of the method-temps that are
part of a suspended method).
