I got the same thing trying to use a Tuple:

  File
"/usr/local/www/Zope3/lib/python/zope/app/form/browser/itemswidgets.py",
line 56, in CollectionInputWidget IInputWidget) File
"/usr/local/www/Zope3/lib/python/zope/component/_api.py", line 103, in
getMultiAdapter raise ComponentLookupError(objects, interface, name)
ComponentLookupError: ((<zope.schema._field.Tuple object at 0xad84a4c>,
None, <zope.publisher.browser.BrowserRequest instance
URL=http://zope.palaceofretention.ca:8080/hey/++preferences++/@@index.html>),
<InterfaceClass zope.app.form.interfaces.IInputWidget>, u'')

It seems the more complex field types might need a custom
widget.  I simply broke the tuple down into its parts and
avoided the lack of a tuple input widget.
