[Zope] about methods not published

[Ibaņez Palomar Juan David]

I've developed a product, the published class is:

def D(Folder, RoleManager):
  def __init__(self):
    """ """
    ...
    self.ps = PersistentMapping()
    ...

  def m(self):
    """ """
    <whatever>


Where ps stores P objects:

class P:
  """ """
  def m(self):
    """ """
    <whatever>


The browser finds the D's method ("mysite/m") but no the P's one
("mysite/ps/key/m").



With Bobo I never had this problem.
Why Zope doesn't publish the P's method?



Thanks,
David
