I've implemented a custom TALES namespace that works fine when tested in the browser, but blows up in doctests. Anybody seen behavior like this? It appears that during the test, my adapter is looked up fine, but later when we try to traverse to the method, we end up with a zope.security._proxy._Proxy wrapper that hides the existence of my methods. Just to reiterate, the same code *works fine* when running Zope for real, and I only see this failure during tests. Here's the tail end of a test / pdb session: 41 def traverse(self, name, furtherPath): 42 -> subject = self._subject 43 __traceback_info__ = (subject, name, furtherPath) 44 attr = getattr(subject, name, _marker) 45 if attr is not _marker: 46 return attr 47 if hasattr(subject, '__getitem__'): (Pdb) n

/home/pw/builds/slinktopp.openplans.org/builds/20081210/opencore/lib/zope/lib/python/zope/traversing/adapters.py(43)traverse() -> __traceback_info__ = (subject, name, furtherPath) (Pdb) n /home/pw/builds/slinktopp.openplans.org/builds/20081210/opencore/lib/zope/lib/python/zope/traversing/adapters.py(44)traverse() -> attr = getattr(subject, name, _marker) (Pdb) p subject <opencore.tales.utils.OpencoreTales object at 0x9840510> (Pdb) p name 'member_title' (Pdb) p subject.member_title *** AttributeError: <exceptions.AttributeError instance at 0x8a02518>

This appears to indicate that the OpencoreTales instance itself is fine, but the security wrapper is preventing attribute access. And here's my zcml: <adapter for="*" provides="zope.traversing.interfaces.IPathAdapter" factory=".utils.OpencoreTales" name="opencore" trusted="true" /> <content class=".utils.OpencoreTales"> <require permission="zope2.View" attributes="setEngine pretty_date project_noun member_title" /> </content> And here's the relevant part of the implementation: class OpencoreTales(object): component.adapts(interface.Interface) interface.implements(IPathAdapter) def __init__(self, context): import pdb; pdb.set_trace() self.context = context def member_title(self): return member_title(self.context) ...
