Oh, and another related (pun unavoidable) problem.

ScheduledRouting <->> ScheduledBatch, ScheduledRouting Owns ScheduledBatch, the delete rule is Cascade, and scheduledRouting is a required relationship in ScheduledBatch.

Yet when I delete a ScheduledRouting, I get the same validation error, only stating "the the scheduledRouting property of ScheduledBatch must have a ScheduledRouting assigned"

Ahg. Why are my delete rules and ownership settings being ignored?! I did go look at the .plist files and verified that they reflect what the settings are in the GUI, just to be sure.

Yes, it's required, but the object that is triggering the validation error should be long gone!

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.
