I have two classes a Container type class and another class that is ' contained ' by that class. The contained class, CompoundKeyMapItem, represents an alternate implementation of an object held in a Map, and uses a Compound Primary Key. The contained class therefore uses an @IdClass. This all works

me what to expect. I have a container class EContainer that is reponsible for maintaining a "map" of items ... , contains a field, "cont", that is derived from ECompoundKeyMapItem's container field via the @MapsId ... "ECompoundKeyMapSubItemId" class, which contains a field "prnt" which is derived from ECompoundKeyMapSubItem's
