Perhaps. It's hard to judge from your code. If you can produce a failing
unit test for Five, demonstrating a particular bug in Five, then we can
start debugging. At this point it's hard to see what you're doing where
etc. Of course, this mandates that you can find a very small set of
circumstances where this occurs -- simply turning your product into a
test will hardly make it more understandable ;).

The root folder (OFS.Application.Application) is not traversable by
default. Hence you won't be able to look up Zope3y things there.

No idea what "correctly" means. It's supported, albeit in an awkward way
regarding the content_factory. The tests demonstrate its behaviour well,
though.
