I received an error message when attempting to delete an object: Error Value: examples does not exist 'examples' is a folder from the Zope tutorial. In my messing around, I have found that this occurs because OFS/ObjectManager, in method _getObj, calls (more or less): hasattr(aq_base(self), id) This returns 0 unless I change it to: hasattr(self, id) Further checking shows that self is of type Acquisiton.ImplicitAcquirerWrapper but that aq_base(self) is of type OFS.Folder.Folder. Is this a bug? Is my ZODB hosed (I do a lot of weird stuff)? Any workaround besides changing the code, deleting the objects and changing the code back? Any side-effects to that approach? What did I do to get it like this? -- John Ziniti Channing Laboratory Brigham and Women's Hospital 181 Longwood Avenue Brookline, MA 02115 john.ziniti@channing.harvard.edu
