Thanks for all the suggestions. Calling the methods from
takeValuesFromRequest() achieved what I was wanting. That's another
part of WO I am now more comfortable with, where a week ago it was too
daunting to investigate.

There are two basic ways for bindings to be sent back and forth. The
most
basic is to let WO do it for you---this is the default. When WO does
it
for you, I believe that bindings are exchanged at the beginning and end
of each of the request-response control points: appendToResponse,
takeValuesFromRequest, and invokeAction. However, I don't know the
details of exactly how and when this works----my general principle is
that if you find yourself needing to know the details, you should move
on
to the second way of sending bindings back and forth.
Hope this helps as an introduction.

With the help and input from Andrew (and Art), my page is continuing
to
progress and I am feeling quite pleased with my new knowledge.
The thing I am wanting to do now (aren't I ever satisfied?) is to
access methods in the sub-component. For instance, the parent provides
the child with the name of an entity. The child then needs to do a
fetch and perform calculations to get the result to display.
I would like to know where I should call those methods? In particular,
at what stage are the binded variables set? I have tried calling the
methods from the constructor (didn't really expect it to work), and
from the awake() method.
Each time the bound variable was still null. I also added the method
ensureAwakeInContext() but this didn't seem to have an effect.
My end result was to use the method valueForBinding() to set them
explicitly, but is this really necessary?
Any suggestions?
ray.
