First of all, thanks for the references.  I'll check them out.

Well, I have an application page which contains a list (one kind of
WAComponent) of anchors for choosing subviews.  Depending on the choice a
render a different instance of a subclass of WAComponent.  It's a rather
traditional banner/tab/subpage layout, with different instances of
WAComponent subclasses for each.

One of these WAComponent subclasses is displayed as an interactive session
(I call it a SessionPage), like a transcript.  I add some more text or an
images to the transcript as the session progresses.  Each next text item or
image is added as a child WAComponent to the SessionPage.  I would like to
reload and render just that instance of SessionPage without reloading the
entire page.  I need this for two reasons:

- The back button really doesn't suit this kind of application.  So if I
presume that if don't reload the whole page there's no way for this to be an
issue.
- I want the user to experience a smoother kind of appearance instead of
redrawing the whole page every time.

I guess I'd also like to avoid reloading the whole page when the user
switches to a different subview.

Thanks for any ideas.

What I totally forgot is that both SeasideAsync and Scriptaculous come
with examples/tests.

That should be simple with either of them.

Depending of what parts you want to update on which actions this can
be anywhere from simple to hard. If it is really just appending at
some "Transcript" is should be doable:
Maybe you want to have a look at the updater demo under the ajax menu at:
