Hi all!!! I'm working on a project that uses Zope (2.5.0) , but most of the work is done in Python (currently 2.1). The thing is that I'm trying to use the Python's class Transience to create a transienteObjectyContainer that calls a method each time an object contained in it (mostly session objects) expires. The docs say that I can do this by defining a 'delNotification' when I create that object. So far so good... But when a call the class __init__ with an callable method, it is executed in compilation time, which means that the method is executed right away, insted of being executed when the object expires. I´ve also tried to pass that method as a string (path+method_name), but Zope asks for the Zope path, and not for the FS path that is used in Python. I'm sure I'm missing the big picture here, so if there's anyone out there that knows how i can do this, it would help a lot :) Cheers Gil
