[Zope] ?Calling a Zope method from a Zope product?

[Julián Muñoz Domínguez]

I try to call a python script from a Zope product developped in python,
from a function which is a thread:

_thread=threading.Thread(None,self._checkExpired)
_thread.setDaemon(1)
_thread.start()


def _checkExpired(self):
   if hasattr(self,'onSessionExpire'):
      self.onSessionExpire()


onSessionExpire() is the python script I want to launch.

The error I have on the console is:

  File "/home/julian/Zope/lib/python/Products/CookieLess/Session.py",
line 289, in _expireSession
    self.onSessionExpire()
AttributeError: __call__



I am not sure of what is happening, have you an idea ???
(Zope is 2.4.1)
