Hi Shane, Toby .. Set Tardis for http://mail.zope.org/pipermail/zope-dev/2003-February/018837.html
All I can think is that that object 'basic' lacks context for some reason (i.e. lacks an acquisition wrapper?). I can't think why it lacks context .. we use that idiom all over the app, and don't normally get any problems.
That's all I can think of also. Try examining basic.aq_chain.
It looks like bad interaction with ZUnit: (Pdb) license.propertysheets.basic <ZInstanceSheet instance at 9a6f350> (Pdb) license.propertysheets.basic.aq_chain [<ZInstanceSheet instance at 9a6f350>, <License_PropertySheetsClass instance at 9a6f128>, <License instance at 9e19038>, <Specialist instance at 99ae6d8>, <Specialist instance at 996acd0>, <Folder instance at 9cad3b0>, *** AttributeError: testsRun 'testsRun' is an attribute that is set in ZUnit.TestMonitor I'm poking about in ZUnit now .. benightedly .. Here is the code context in which the above obtains:: # Create a new reminder and reference it from the License reminder = container.addInstance(no_redir=1) import pdb; pdb.set_trace() #DBG We are here. This fails: license.propertysheets.basic.manage_changeProperties( {reminder_id_property: reminder.id}) That is in a Script (Python). The 'license' instance was created in the calling Script (Python), and passed in as parameter. Calling sequence: addLicenses (called from a ZUnitExternal test suite) -> addLicense (creates license instance) -> doRemindersForLicense(license) (creates reminder instance; calls license.propertysheets.basic.manage_changeProperties) Perhaps interestingly, reminder and AUTHENTICATED_USER seem to be OK, and license and context do not: (Pdb) reminder.aq_chain [<Reminder instance at 9c39bb0>, <Specialist instance at 99682a0>, <Application instance at 9968a48>, <RequestContainer instance at 8fd9e68>] (Pdb) license.aq_chain [<License instance at 9e19038>, <Specialist instance at 99ae6d8>, <Specialist instance at 996acd0>, <Folder instance at 9cad3b0>, *** AttributeError: testsRun (Pdb) context.aq_chain [<Specialist instance at 99682a0>, <Specialist instance at 99ae6d8>, <Specialist instance at 996acd0>, <Folder instance at 9cad3b0>, *** AttributeError: testsRun (Pdb) context.REQUEST.AUTHENTICATED_USER.aq_chain [jean, <LoginManager instance at 996f588>, <Application instance at 9968a48>, <RequestContainer instance at 8fd9e68>] -- Jean Jordaan http://www.upfrontsystems.co.za
