[Seaside] Re: Seaside Async and form submission

[Ryan Simmons]

Had a quick look at Seaside Async, can't see that it supports
submitting a whole form.

If you need to use Seaside Async, you could use liveCallbacks on all
the selects but link them up to a momento then commit the momento back
to your model when the user clicks on the anchor
