Hi all,
This is very confusing, and I know it should be a very simple thing.
I have a the following relationship that is marked as Owns
Destination,
ManufacturingSchedule <->> ScheduledRouting
When I remove the ScheduledRouting from the ManufacturingSchedule's
scheduledRoutings() relationship by calling
removeObjectFromBothSidesOfRelationshipWithKey
(scheduledRoutingToDelete, "scheduledRoutings");
on the ManufacturingSchedule, the ScheduledRouting is not being
deleted when I call editingContext().saveChanges(). Instead I'm
getting a validation error:

Why isn't it just deleting the ScheduledRouting object on save? All
of ScheduledRouting's relationships are either Cascade or Nullify,
so I know that it isn't being held onto because of a delete rule.
It might be some variation of this:
