Hello, I am working on a Python Product (subclass of ObjectManager) that creates some instances of a few ZClasses inside itself when constructed. Currently, I do this as follows: CONTROL_PANEL = None def manage_addMyClass(self, id, title='', REQUEST=None): global CONTROL_PANEL if CONTROL_PANEL is None: CONTROL_PANEL = self.Control_Panel self._setObject(id, MyClass(id, title)) ... class MyClass(...): def __init__(self, id, title=''): self.id = id self.title = title ob = CONTROL_PANEL.Products.MyProduct.MyClass('myId') ob.id = 'myId' self._setObject('myId', ob) which works fine, until I need to use CONTROL_PANEL from somewhere else before manage_addMyClass is called (currently, I am trying to upgrade existing instances in __setstate__). Inside __setstate__, self.Control_Panel throws an exception, for understandable reasons. So, I get the feeling I am going about this incorrectly. I grep'd the source last night, looking for a getApplicationInstance() method, or something similar, but found nothing. AFAICT, there is no easy way to get ahold of the one true Application object without having a reference to an object in the ZODB and calling getPhysicalRoot(). Did I miss something? Is there a better way to do what I am trying to do? --Jeff --- Jeff K. Hoffman 704.849.0731 x108 Chief Technology Officer mailto:jeff.hoffman@goingv.com Going Virtual, L.L.C. http://www.goingv.com/
