Hi everyone, Clicking on the "Advanced" tab of a ZSQL method produces a traceback. It appears to be triggered by an old installation of the pre-Ron Bickers version of Photo. (That one used ZClasses, IIRC.) Any hints about how to fix this? Here's the traceback: Error Type: SystemError Error Value: Failed to import class _ZClass_for_ZPhotoAlbum from module Products.Photo Traceback (innermost last): File /home/wilson/zope/2.5.1b1/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /home/wilson/zope/2.5.1b1/lib/python/ZPublisher/Publish.py, line 114, in publish File /home/wilson/zope/2.5.1b1/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: qry_citylist) File /home/wilson/zope/2.5.1b1/lib/python/ZPublisher/Publish.py, line 98, in publish File /home/wilson/zope/2.5.1b1/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: manage_advancedForm) File /home/wilson/zope/2.5.1b1/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: manage_advancedForm) File /home/wilson/zope/2.5.1b1/lib/python/Shared/DC/Scripts/Bindings.py, line 252, in __call__ (Object: manage_advancedForm) File /home/wilson/zope/2.5.1b1/lib/python/Shared/DC/Scripts/Bindings.py, line 283, in _bindAndExec (Object: manage_advancedForm) File /home/wilson/zope/2.5.1b1/lib/python/App/special_dtml.py, line 172, in _exec (Object: manage_advancedForm) File /home/wilson/zope/2.5.1b1/lib/python/Shared/DC/ZRDB/DA.py, line 476, in manage_product_zclass_info (Object: qry_citylist) File /home/wilson/zope/2.5.1b1/lib/python/ZODB/Connection.py, line 472, in setstate SystemError: (see above) --> -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.org | http://www.zope.com W.
