Subject Re: Bug when persisting two related objects
Date Thu, 10 May 2007 15:56:21 GMT
Are the two types related by inheritance?  If two classes in an  
inheritance hierarchy use the same id class, then every instance of  
both classes must have a distinct id value.  If you want instances in  
inheritance-related classes to be able to have the same id values,  
then you must use different id classes for different classes in the  
inheritance hierarchy.
