[Seaside] Split form

Hi Jeff,

I hope I am correct with what I say, but I am not 100% sure. I think you
can use Ajax for this. Since you serialize the form you won't need a HTML
form tag at all. That is, no need of HTML form (unless it does not harm if
you want it as for displaying/css things), and instead of using submit
buttons, you use normal buttons with ajax calls and serialization. Example:

html button bePush; onClick: (html jQuery ajax serialize: (html jQuery:
'.formToSubmit' ) script: [ :s | self doSomething.
] ); value: 'Click me'.

The basis here is:

1) use bePush because you are using Ajax and so buttons do NOT have to be
2) The magic here is #serialize: which will serialize and invoke callbacks
for those inputs. And the good thing is that it accepts a jQuery as the
argument of what to serialize. So you can say, for example, all those
elements with css class '.formToSubmit'.  And then, when you render forms 1
and 3, you add css class 'formToSubmit'. If the component is very very
large, you can reduce the jquery search for performance (like checking
those elements form AND css class formToSubmit etc...).
3) Note that since this is ajax, you could have a couple of headaches. For
example, doing an #answer: from within the #script: of the ajax call is not
easy. Also, if you are used to normal request, you would re-render
everything automatically. Here, unless you do something inside #script: it
won't refresh anything. So depending on what you need to you may need to
refresh something from there.

If you are used to Ajax this will be very very easy. If you need more help,
let me know.
