InvalidCastException from FindDirty on many-to-one association with property-ref to composite-id class
Description
When one class (A) references another (B) using a composite-id, through a many-to-one association with a property-ref, all operations appear to work normally except for the update – which fails on the call to FlushDirty on A with a new reference to a B (either new or existing B). It seems as if the flush dirty ignores the property-ref association and attempts to ascertain whether the property is dirty by comparing the property-ref's actual value (which is an integer) to the new B's composite identifier.
I will attach a test ASAP.
Error:
NHibernate.Test.NHSpecificTest.NH1234.BugTestCase.PropertyRefCompositeIdDoesNotFlushProperlyOnUpdate: System.InvalidCastException : Unable to cast object of type 'System.Int32' to type 'NHibernate.Test.NHSpecificTest.NH1234.WidgetCategory'.
