[Zope3-Users] z3c.form and subforms in an AddForm?

[Mats Nordgren]

Thanks Stephan,

I have now got the sub form to render in browser.  Much appreciated.

A few more questions though.  In the create method, the data is only the
parent data.  The self.widgets.extract() returns only parent data.  The only
place I see the sub form data is in self.request.form.  What is the best way
to extract the data and create your object?

Perhaps unrelated but I had this working before. I'm using formui and I'm
getting a "TraversalError: (<ErrorViewSnippet for RequiredMissing>,
'widget')".  I tried to trim out all the sub-form stuff I've messed around
with and replaced a simple object with two textlines one of which is
required.  This happens when I'm submitting the form without an entry in
required field.  With data it works just fine and adds the object.  The
addform is using the macro:form from formui.  Any ideas as to where this
comes from and how I can fix it?

Thanks,

Mats Nordgren
