Having still more problems with this installation of Zope 2.1.6 and PTK 0.7.1... I've got several (seems that the number is growing) objects that appear in my ZCatalog, and show up on my site, but refuse to let me edit, move or delete them. Try to delete the object and get the following error: ------------------------------------------------------------------------------------------------------------------- Error Type: ValueError Error Value: Uncatalog of absent id '/portal/Members/demo4/D_Application' Traceback (innermost last): File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 214, in publish_module File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 179, in publish File C:\PROGRA~1\DEV_PO~1\lib\python\Zope\__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 165, in publish File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_delObjects) File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: manage_delObjects) File C:\PROGRA~1\DEV_PO~1\lib\python\OFS\ObjectManager.py, line 401, in manage_delObjects (Object: ElementWithAttributes) File C:\PROGRA~1\DEV_PO~1\lib\python\OFS\ObjectManager.py, line 273, in _delObject (Object: ElementWithAttributes) File C:\Program Files\dev_portal\lib\python\Products\PTKBase\PortalContent.py, line 226, in manage_beforeDelete (Object: D_Application) File C:\Program Files\dev_portal\lib\python\Products\PTKBase\PortalContent.py, line 213, in unindex_object (Object: D_Application) File C:\PROGRA~1\DEV_PO~1\lib\python\Products\ZCatalog\ZCatalog.py, line 357, in uncatalog_object (Object: ElementWithAttributes) File C:\PROGRA~1\DEV_PO~1\lib\python\Products\ZCatalog\Catalog.py, line 373, in uncatalogObject ValueError: (see above) ------------------------------------------------------------------------------------------------------- Updating the ZCatalog doesn't help, nor does clearing it out and re-populating it. I've searched through the mailing list archives and all the advice says to delete the ZCatalog, delete the trouble items, then undo the Catalog deletion. So I've tried to delete the ZCatalog 'SiteIndex' and then tried to delete the object and get this different error: ----------------------------------------------------------------------------------------------------------- Error Type: AttributeError Error Value: SiteIndex Traceback (innermost last): File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 214, in publish_module File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 179, in publish File C:\PROGRA~1\DEV_PO~1\lib\python\Zope\__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 165, in publish File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_delObjects) File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: manage_delObjects) File C:\PROGRA~1\DEV_PO~1\lib\python\OFS\ObjectManager.py, line 401, in manage_delObjects (Object: ElementWithAttributes) File C:\PROGRA~1\DEV_PO~1\lib\python\OFS\ObjectManager.py, line 273, in _delObject (Object: ElementWithAttributes) File C:\Program Files\dev_portal\lib\python\Products\PTKBase\PortalContent.py, line 226, in manage_beforeDelete (Object: D_Application) File C:\Program Files\dev_portal\lib\python\Products\PTKBase\PortalContent.py, line 213, in unindex_object (Object: D_Application) File C:\Program Files\dev_portal\lib\python\Products\PTKBase\PortalObject.py, line 318, in getCatalog (Object: DemoPortalBase) AttributeError: (see above) -------------------------------------------------------------------------------------------------------- It looks like a similar problem was fixed on a recent version of Zope according to the history file, but so far all attempts at moving this project over to a more recent version of Zope/PTK have been less than successfull. As always, any and all comments/ suggestions/ help are very much appreciated...I've found this mailing list archive to be the most helpful documentation available so far. Thanks, Dave.
