[Zope] has_permission in PythonMethod

I have this (internal) PythonMethod called filtered_meta_types user=self.REQUEST.AUTHENTICATED_USER meta_types=[] if callable( self.all_meta_types ): all=self.all_meta_types() else: all=self.all_meta_types for meta_type in all: if meta_type.has_key( 'permission' ): # this is always false :( if user.has_permission( meta_type['permission'], context ): meta_types.append( meta_type ) else: meta_types.append( meta_type ) return meta_types I do not get why the 'has_permission' condition is always false If I mimic this function in DTML (yuk), it *does* work. TIA, Stefan -- Things work better when plugged in
