Document Actions
Functional testing: The object at x has an empty or missing docstring.
This Error Reference applies to:
Plone 2.1.x, Plone 2.0.x
This Error Reference is intended for:
Any audience.
Cause
__bobo_traverse__ fails in functional testing, because getattr("actionname") for Plone object returns None - The actions of your object are not accessible. This causes "missing doctstring" message, because None object has no docstring (surprise, error message is not very helpful). When using quick installer in ATFunctionalSiteTestCase, method PortalTestCase._refreshSkinData() is not called. This is needed for action registration.
Solution
In your TestCase.afterSetup(), call PortalTestCase._refreshSkinData()
self.qi = self.portal.portal_quickinstaller
self.qi.installProduct('Archetypes')
self.at = self.portal.archetype_tool
self.qi.installProduct('PloneLocalFolderNG')
# Calling this ensures that PloneLocalFolderNG actions are registered propeply
self._refreshSkinData()
