Hmm ... how? It just doesn't return the utility as expected (it returns None). There is no error shown in any way. I used pdb to trace the problem down to zope.component.registry.queryUtility . The call to self.utilities.lookup returns None but should return a persistent instance of my InitIndicator class. The call to lookup() is not tracable - I guess it's written C(|++) . However - watch this: > /ZOPE/zope3/src/zope/component/registry.py(132)queryUtility() -> return self.utilities.lookup((), provided, name, default) (Pdb) [reg for reg in self.registeredUtilities() if reg.provided is IInitIndicator] [UtilityRegistration(<LocalSiteManager ++etc++site>, IInitIndicator, u'fb', initindicator, '')] (Pdb) self.utilities.lookup((), provided, name, default) (The initindicator utility is registered but lookup() can't find it.)
