[RO] Returns 404 for empty List (while should 200)

Dan:
I tracked down the issue I think ... there's a method called route(...) where we pass in a PackedManagedObject that wraps the empty List (or rather, Can at this stage), but what we get out is an EMPTY ManagedObject. The RO viewer then interprets that as a 404.
[..] the behaviour is because route(...) calls in turn ManagedObjects.isNullOrUnspecifiedOrEmpty(...) [line 70]
