Cool.

Just access your sub-form. In the new "Address Book"  demo of z3c.formdemo, 
the sub-forms are responsible of creating sub-objects, so there you simply 
can ask for the content like this: form.subForm.getContent(). In edit forms 
you do not have to do anything, because you are modifying thos sub-objects.

Another approach is to ask the widget manager for the data:

form.subform.widgets.extract()

No idea. Could you provide the complete traceback?
