I installed the latest and greatest products, updating some existing ones. Some of the products have .zexp components. For Zwiki I moved the file under imports, and then attempted to import it I get the error shown below. I can not find an object named zwiki (as opposed to ZWiki) in my products folder, nor at the top level. A lower level folder has an item called zwiki; I do not believe it is eligible for acquisition, because it's in a separate branch. I ran into a similar problem with ZDiscussion, but in that case I was able to delete the product and then do the import. I'd appreciate any clues about this particular problem, or about the general question of how to import safely when one already has objects using earlier versions of the classes. ----------------------------- error and traceback below here------------------------------------------- The object zwiki does not support this operation Traceback (innermost last): File /web/main/src/Zope/2.1.0b2/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /web/main/src/Zope/2.1.0b2/lib/python/ZPublisher/Publish.py, line 179, in publish File /web/main/src/Zope/2.1.0b2/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File /web/main/src/Zope/2.1.0b2/lib/python/ZPublisher/Publish.py, line 165, in publish File /web/main/src/Zope/2.1.0b2/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_importObject) File /web/main/src/Zope/2.1.0b2/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_importObject) File /web/main/src/Zope/2.1.0b2/lib/python/OFS/ObjectManager.py, line 479, in manage_importObject (Object: ElementWithAttributes) File /web/main/src/Zope/2.1.0b2/lib/python/OFS/CopySupport.py, line 374, in _verifyObjectPaste (Object: ElementWithAttributes) Copy Error: (see above)
