Hi, there's a bug in OFS/Traversable.py line 169 (on Zope 2.3.0 and 2.3.2) in unrestrictedTravese() there's: --- CUT --- if name[0] == '_': # Never allowed in a URL. raise 'NotFound', name --- CUT --- but when calling restrictedTraverse with only '/' as the path argument the test above raises an IndexError, and it's possible that the rest of the function unrestrictedTraverse doesn't work correcly even when correcting this bug with a "if name and name[0]=='_'" (UNTESTED). Example: make a Python script, which has only the following line: --- CUT --- return repr(context.restrictedTraverse('/')) --- CUT --- Click on the Test tab, that's it ! Theorically and if I understand correctly what restrictedTraverse and unrestrictedTraverse are for, it should return the top level object i.e. the root folder object or application object. hoping this helps Jerome Alet
