    I'm trying to delete a DataObject with a dependent relationship. If I resolve the relationship first, it works. If I don't resolve it first, I get a ClassCastException (in both 1.03 and 1.04).

    DataContext's delete method uses DataObject's readPropertyDirectly to get the related object, then casts it to DataObject. If the relationship hasn't been resolved, readPropertyDirectly returns a RelationshipFault, not a DataObject. Hence the ClassCastException.

    Should readPropertyDirectly be returning a RelationshipFault or should it be resolving the relationship and returning the related object. The latter behaviour seems safer, but is it correct?

    Thanks,
