So you might still be on the JavaScript wrapper hiding the Java API, not the
actual Java object.

I really wondered about this one as well. What's Widget actually? There is no
import in this file, only thing I found was the reference to/ defineClass of
ScriptableWidget.

I'd wonder if CForms itself depends on Dojo. Dojo should only be used on the
client side. So I *guess* you are wrong, but I don't know actually.

What does it return? Maybe it points to something.

CForms has a binding framework, with which you can bind your form model to a
data model (be it objects or XML). I thought before programming binding of form
model to a page local and back you could reuse that one. But if PageLocal has so
much auto magic you don't need it.

Why?

Can't follow again :( In my pseudo code I did some traversing of the form model
by using getChildren() (if it would be available). This should give you access
to the nested widgets.

:)
I'm quite patient as long as there is some progress and the counterpart is
willing to investigate on itself as well. That seems to be the case with you ;)
