Hi list I've seen others having problems with this as well .. I made a ZClass, not consciously touching anything about PTK. Now when I export it ('ccDoc.zexp') and import it into another Zope, I get:: Error Type: ImportError Error Value: No module named PTKDemo.PersistentUserSource Traceback (innermost last): File C:\programs\ZopeJean\lib\python\ZPublisher\Publish.py, line 214, in publish_module File C:\programs\ZopeJean\lib\python\ZPublisher\Publish.py, line 179, in publish File C:\programs\ZopeJean\lib\python\Zope\__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File C:\programs\ZopeJean\lib\python\ZPublisher\Publish.py, line 165, in publish File C:\programs\ZopeJean\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_importObject) File C:\programs\ZopeJean\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: manage_importObject) File C:\programs\ZopeJean\lib\python\OFS\ObjectManager.py, line 488, in manage_importObject (Object: ElementWithAttributes) File C:\programs\ZopeJean\lib\python\OFS\ObjectManager.py, line 238, in _setObject (Object: ElementWithAttributes) File C:\programs\ZopeJean\lib\python\OFS\ObjectManager.py, line 254, in manage_afterAdd (Object: ElementWithAttributes) File C:\programs\ZopeJean\lib\python\ZClasses\ZClass.py, line 412, in manage_afterAdd (Object: ccDocClass) File C:\programs\ZopeJean\lib\python\ZClasses\ZClass.py, line 373, in _register (Object: ccDocClass) File C:\programs\ZopeJean\lib\python\ZODB\Connection.py, line 396, in setstate File C:\programs\ZopeJean\lib\python\ZODB\Connection.py, line 205, in _persistent_load (Info: What do I have to do with PTKDemo?? -- Jean Jordaan -- technical writer -- Mosaic Sofware -- Zope 2.1.6 on WinNT and W2K _______________________________________________ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
