Thanks Michael,
 There is indeed something missing :
 ComponentLookupError: ((
  zope.schema._bootstrapfields.Int object at 0x01A83610 , 
  zope.publisher.browser.TestRequest instance URL=http://127.0.0.1 ), 
  InterfaceClass zope.app.form.interfaces.IDisplayWidget , u'')
 My problem has nothing to do with containers, since my interface is
 not a container. It seems that zope can't find the adapters for the shema 
fields, even when 
 I register them by code. I really don't know what to do from now.
 The fact is I use AJAX, so I don't need to register my views, I just
 call them from code to use the generated html as a response to a
 javascript call that then update my page.
 
 Thanks,
 
 Stéphane

There seems to be something missing before ", http..." ... did you copy 
it form the browser output?

Guess out of the dust: does the interface of the object you want to 
display have a zope.app.container.constraints.containers directive?

This thread seems similar to your problem.
