[Seaside] Accepting input from parent & child components

[Mark Bratcher]

Hello

I have a WAComponent that displays some input fields, and it renders a 
child component that displays additional, related input fields. For 
example, if I'm having the user edit an invoice, there are general items 
on the invoice (like special terms of payment, etc) and then there are 
invoice line items, which are rendered and input via a subcomponent.

The parent input fields and subcomponent input fields are within the 
same html `form`. However, when I click the submit button (done at the 
parent level), only the input items rendered by the parent are 
recognized. Any inputs provided by the user through the embedded, 
rendered subcomponent are ignored.

I bought and have been reading Dynamic Web Development With Seaside, but 
it does not address this case.

Is it possible to do what I'm attempting to do?

Thank you
Mark
