[Grok-dev] schema.Time() ComponentLookupError wierdness...

I get the wonderful...

   ComponentLookupError: ((<zope.schema._field.Time object at  
0x3480190>, <zope.publisher.browser.BrowserRequest instance  
URL=http://localhost:8081/dynasales/default/project_1/sales_desks/ 
sales_rep_1/dashboard>), <InterfaceClass  
zope.app.form.interfaces.IInputWidget>, u'')

...when I am trying to render a widget based on the following schema:

   class ISalesAction(Interface):
     """
     This is actual text in a section.
     """
     due_date = schema.Date(title=u"Due date", required=False)
     due_time = schema.Time(title=u"Due time", required=False)
     type = schema.Choice(title=u"Type", values=('ToDo', 'ToCall'))

The actual object being passed has been instantiated like this:

   class SalesAction(grok.Model):
     interface.implements(interfaces.ISalesAction)
       def __init__(self):
         self.type = None
         self.due_date = None
         self.due_time = None

There is no problem with the due_date widget. As usual with comonent  
lookup errors I am at a loss... :) Full trace bellow. When I omit the  
"due_time" field, it all renders fine. Any ideas?

Note, the pagetemplate is called by another pagetemplate which in  
turn is called by another pagetemplate. But I don't think this should  
make any difference.
