[Zope-dev] subobject in BaseObject

Archetypes has a cool feature: when MS doc are transform to html, 
pictures in the doc are stored as subobject of the content.

After many tests, the feature works only when anonymous can view the 
content. Or the picture will not show even I login at admin.

I traced it, and found it fails at the last step: it returns the correct 
wrapper object, but fails when call the following __call__ method(no 
permission). It is quite strange since the 
__allow_access_to_unprotected_subobjects__ is already in the Wrapper class.

Any hint for me?

# the Wrapper class in BaseObject.py:
class Wrapper:
     """wrapper object for access to sub objects """
     __allow_access_to_unprotected_subobjects__ = 1

     def __init__(self, data, filename, mimetype):
         self._data = data
         self._filename = filename
         self._mimetype = mimetype

     def __call__(self, REQUEST=None, RESPONSE=None):
         if RESPONSE is None:
         if RESPONSE is not None:
             mt = self._mimetype
             name =self._filename
             RESPONSE.setHeader('Content-type', str(mt))
                                'inline;filename=%s' % name)
             RESPONSE.setHeader('Content-Length', len(self._data))
         return self._data
