[Seaside] Accepting input from parent & child components

Thank you for the prompt reply, Otto.

I did a "view source" and only found one `<form ...>` very early in the 
file, and one `</form>` near the very end. So I believe there is only 
one form tag in the HTML.

Also, I didn't not before, than I'm using the WAFormDecoration in the 
parent, if that matters.

By "recognize", I mean that I'm not seeing evidence that the callbacks 
for changed fields in the child are being triggered.

I'm not sure how to determine the version of Seaside I have. I am using 
GNU Smalltalk 3.2.91-b98173d, so it's whatever Seaside package revision 
they've included with that.
