I am not familiar with z3c.form (being stuck with maintaining a project
based on Zope 3.2 means you don't get to play with new toys).

With zope.formlib you could solve this by passing an initial data dict
to the setUpWidgets call.  Doesn't z3c.form have something like that?

You mentioned that you looked at the source where the widgets were
updated.  I suggest you look at the place where the widgets are created
& initialized.
