I'm trying to move our sites from Zope 2.5.1 to Zope 2.8.1-final and I'm receiving an error with this script: http://www.zope.org/Members/johntynan/feedparser/ In particular, I receive the following error, when using the attached page template "nprnews.pt": "Unauthorized: You are not allowed to access 'a particular list' in this context" (see traceback.txt attached). This page template renders an rss feed that has been transformed into a dictionary (see "dictionary.txt" attached) via a python script ("feedscript") which calls an external method ("newsfeed") which uses Mark Pilgrim's feed parser to parse the xml into a python data type. If I run the python script or the external method directly (via the "test" tab in the ZMI) I have no problem viewing all the properties of the rss feed. However, if I use the page template, I still receive this error. I've tried to get around this by running the python script using a proxy role of manager or owner, but I still receive the same error. Any suggestions you might have are appreciated. John Tynan - webmaster KJZZ.org / KBAQ.org 480.774.8462
