Or, do you have both the flattened relationship and the unflattened relationship to the join table present in your model? Be careful with this. You have to keep both updated. WO won't keep them in sync automatically. I only use flattened relationships when I know my app won't be modifying the relationship (i.e. in read-only situations). Otherwise, I don't use them or I create a cover method in my EO to simulate them using valueForKeyPath.

I have a flattened relationship between CollectionDescription and
Content.

Bad things seem to happen when the underlying relationships of a flattened relationship are class properties. That's not true in your eomodel, right?
