Hi all!
Some days ago I begin this threat: http://www.mail-archive.com/zope@zope.org/msg26355.html

Dieter point me to the solution and I try something like:

def __bobo_traverse__(self, REQUEST, nombre):
        obj = getattr(self, nombre, None)
        if obj is None:
            self.REQUEST.set('TraversalRequestNameStack', self.REQUEST["TraversalRequestNameStack"] + [nombre])
            resultado = self()
            if type(resultado) == type(unicode()): return WrapperUnicode(resultado)
            elif type(resultado) == type(str()): return WrapperStr(resultado)
            else: return resultado
        return obj

and the wrappers:

class WrapperStr(str):
    __roles__ = None

class WrapperUnicode(unicode):
    __roles__ = None

But when I try to launch this zope raises a NotFound exception

If I inspect de content of resultado I could see an unicode string then the WrapperUnicode is used to wrap the result

Can you point me where the problem is, please?

Thanks a lot!
