Josef, Thank you. I had done everything you mentioned, but didn't see the ScheduleList object located at the root level of Zope. Removing that solved the problem. Thanks again. Barry --- Josef Meile wrote:
Hi Barry,
I'm getting an attribute error when I try to run Zope 2.7.6, which is occurring when NauScheduler starts up:
AttributeError: ignoreLater
[...]
schedule.ignoreLater()
AttributeError: ignoreLater
It means that the object schedule doesn't have or can't access a method called ignoreLater. With "it can't access" I mean that the object is there, but it is broken.
Looking at the source code of the NauScheduler, I saw that the __init__.py file checks for an instance of the "ScheduleList" class, which has the same id and if I'm not wrong it is created the first time that you create a NauSchedulder object in the ZMI, then the absolute path of the new created object is added to a path list inside the "ScheduleList" object. So, it means that somehow you already tried to create a NauScheduler Object, but something when wrong causing either the creation of a broken object or the object wasn't created at all, but its path was stored in the "ScheduleList". And I think that's why you get "AttributeError: ignoreLater" because "None" or a broken object don't have or can't access the ignoreLater method.
So, my suggestion is:
1) Make a backup of your Data.fs 2) Remove the NauScheduler Product from your Products folder. 3) Restart Zope 4) Remove the NauScheduler objects 5) Remove the ScheduleList object. 6) Stop Zope 7) Move the NauScheduler again to the Products folder 8) Restart zope 9) Watch at the console to see if an error is printed 10) If no errors are printed, then try to create a NauScheduler object and see if it works.
I am using NauScheduler on other windows and unix systems. But have not seen this problem before. Can anyone help? Below is the traceback.
Another possibility is that you are using a Data.fs comming from a unix system into a Windows XP PC and somehow the import of the instances wasn't successful. If this is the case, the question is: did you make sure to first install all the products you are using in linux before moving the Data.fs? But I'm especulating here since you didn't give details about the installation (ie: was it a clean zope installation or did you migrate a Data.fs from unix to windows?)
Regards, Josef
