[Seaside] Ports of Seaside - are there useful modules

I'd be happy to give it a try in VisualAge - can you post the TestCase?
And, is this test case a universal case for continuation? Can I test
Dolphin, SmallScript, etc. with it?
My original question was prompted by the fact I have a bunch of code in
Dolphin I'd like to keep there. However, I also have some VisualAge
stuff that would benefit from Seaside.
I really liked the tutorial, and would be happy to pursue further.

Well, Seaside is roughly based on the design of WebObjects, which
doesn't use continuations; the templates and bindings system, the
subcomponent model, the basic session management, etc, would all work
without them: basically you would have to lose the callPage: primitive,
but you'd still have jumpToPage:, and you can do a lot with that. It's
still a lot nicer than, say, SSP.
However, I'd say that continuations make up about half of the advantage
of Seaside; that is, Seaside + continuations is, IMHO, about as much
nicer to work in than WebObjects, as WebObjects is nicer to work in than
JSP & co. So there'd have to be a pretty compelling reason for me to
work in a Smalltalk without them - the choice of Squeak or VW meets my
needs pretty well.
Does anyone know if continuations can be implemented in VisualAge,
anyway? I believe it has thisContext and #swapSender:, does it not? I
can post a small TestCase for them if anyone wants to try.
