[Seaside] Entire html stream in span after html updater

the problem with the attached code is that the JavaScript part of
script.aculo.us is triggering the button callback. This causes Seaside
to abort further callback processing and restart the rendering loop
with a full page render.

Now what can we do about this?

Choose one of these options:

- Instead of triggering the whole form you could just trigger the form
elements you require, in your case the changed select box.

- Change the JavaScript of script.aculo.us not to trigger submit buttons.

- Change the way Seaside processes action-callbacks, this means to
ignore all action callbacks with script.aculo.us requests. This is
quite a deep change to Seaside, so maybe we should rethink that.

Cheers,
Lukas
