Does your skin or at least one super class use IFormLayoutSupport?

Can you tell that kind of fields the schema defines?
Probably there is not widget for one of this fields configured.

Or you can check which fields makes prtobelms with using the select
filter:

fields = z3c.form.field.Fields(ISomeConcent).select('oneWidget')

Try to find the field which makes problems. And then you can
take a look if z3c.form provides a IWidget configured for that
field.

A good thing is alos debug and find out if your request really
provides the FormLayoutSupport. You can do this in the __init__
of your z3c.form class e.g.:

def __init__(self, context, request):
    import pdb;pdb.set_trace()
    super(MyForm, self).__init__(context, request)
    

Also make sure that the configure.zcml of z3c.formui
is included in your project. And you need to define the
skin with soemthing like:

  <zope:interface
      interface="myproject.IMySkin"
      type="zope.publisher.interfaces.browser.IBrowserSkinType"
      name="MySkin"
      />

Seems defently a missing widget if other widget adapter will
be found for the same form.

Hope that helps
