Message Title

In my setup I have an unidirectional one-to-one relation from Person -> Address in the attach test case. The Person has @EmbeddedId which one of it's id's should be cascaded to the Address id.
When I map a @OneToOne relation with @Mapsid with the purpose of cascade the primary key it throw an exception.
