I am having some problems with the Athena toggle widget in a radio
group.  I have successfully created radio groups where I have been
able to specify the radio group at the time the widgets are being
created.  However, I have a situation where I need to be able to
set up a radio group "on the fly."  I'm using WsXc to generate my
widget tree for me, (saves a *lot* of C coding!) and I want to set
the radio group from the createCallback.  A short test program to 
illustrate my problem is below.  Why won't these toggles function
as a radio group?
