[Seaside] Accepting input from parent & child components

[Otto Behrens]

What you have here looks fine to me.

So the next thing I can think of do is to use the debugger to figure
out what is going on.

I would set a breakpoint in WACallbackRegistry >> handle:. This method
maps the names that are posted to the callbacks that are evaluated.
So, this will tell you firstly what fields are posted and then if they
map to the callback registry. If the field is not there, then you know
it is not coming through from the browser. If the callback is not
mapped, then we can try to figure that out from where the callback is
created. This is getting deep into Seaside though...
