Hi! I've got a problem that's bothering me no end. I'm trying to import a file (gskolan.zexp) exported from Zope 2.3.0 into my 2.3.3, but I keep getting the following message: "The object gskolan does not support this operation." I ran this through the Wing debugger to try to figure out where things go wrong, because the Zope debug output only told me the error was in "_verifyObjectPaste". First, I get a KeyError exception in ZPublisher/HTTPRequest.py, line 884, method __getitem__ of class HTTPRequest. The value of the variable key at this time is "__nonzero__". The exception generating the message I see is located at OFS/CopySupport.py, line 440, method _verifyObjectPaste of class CopyContainer. Interesting data: meta_types = ({'name': 'Product', 'action': 'manage_addProductForm'},) mt = "Folder" method_name = None What happens is that the exception is reached because method_name is None, which in turn happens because none of the entries in meta_types has a ['name'] that is "Folder". The only that exists is "Product"! Does this mean I can only import products this way? Because of the KeyError exception, I grepped the documentation for "__nonzero__" and found a bugfix mentioning it from 2.3.1. Could this whole thing be occuring because I'm importing a file exported from 2.3.0 to a 2.3.3? I don't have access to the 2.3.0 server to upgrade it. Maybe I could try installing a 2.3.0, importing, upgrading and then exporting. I'd be very thankful for any feedback on this problem! /Danni
