[Zope] Acquiring object from Products instances

Hi, I've a product that defines a classe ageForm. I've a PythonScript that adds an ageForm instance to a folder. After adding the instance it calls a method on it. This methods tries to access an objects using acquisition. Image I have something like this: + f (Folder) + o (object to acquire) + i (ageForm istance) + s (script that creates i and calls i.m) so the script s is like this: i = f.manageAddForlder ..... i.m () the ageForm method is like this: def m(self): o.doSomething() the ageForm class inherits from SimpleItem.SimpleItem and from a simple Python base class. Any hint? TIA, Luca
