I have a similar problem trying to use a flattened relationship in my
WOUnitTesting.
I have this:
Study <->> StudyPeriod <->> StudySchedule
My flattened relationship periodSchedules is defined in my EOModel for
Entity Study as studyPeriods.studySchedules named "studySchedules".
I create the study, its periods and the periods' schedules using
WOUTMockEditingContext and the createSavedObject and
addRelationshipToBothSides... methods. All works fine when I
enumerated over the realtionships. It passes all of my tests for
custom methods I have. However, whenever accessing my flattened
relationship ("studySchedules"), rather than enumerating over the
to-many relationships, the result is always an empty array.
I am not sure if this is related to the faulting of flattenen
relationships or something specific with using the
WOUTMockEditingContext (not the newest version WOUT2)
Any ideas? Should I just stick to enumeration? It would just be nice
to be able to use the "shortcut" when I need it.
Thanks,
Pete

Yes its expected, at least, I would expect it. When I did the WOII
course in 2001 I think it was mentioned as a reason to not use flattened
relationships, amoung other more obvious reasons. I have not seen any
documentation about it though that I can remember. Perhaps searching the
omnigroup list archive would give you more info.
