Hi all

Finally I solve my problem with Tres Seaver's help (THANK YOU)

I override the __bobo_traverse__ with:

def __bobo_traverse__(self, Request, Name):
  import sys
  if sys._getframe(1).f_code.co_name == "traverse":
   return getattr(self, Name)
  else:
   return self.Propiedad(Name)

self.Propiedad is the fuction than neutralices (I call these mechanism Neutralization) the content of my object

When You executes ZMI sys._getframe(1).f_code_co_name returns traverse

Thanks again Tres Seaver!
