Element Collections
JPA 2.0 Root | Enhancement Request
Issue Summary
JPA 2.0 introduces support for collections of Embeddables and primitives through the @ElementCollection annotation. Support for ElementCollection of primitives will be easily supported through our BasicCollection and BasicMap support and will only require annotation processing updates. Support for lists of Embeddables should be supportable through the AggregateCollectionMapping. Support for Maps of Embeddables will be more difficult and will require completion of the Map Collections support feature.
@OrderBy must also be supported on these collection types.
See section 2.1.5, 9.1.2, 9.1.4, 9.1.7, 9.1.11 and 9.1.35 for details.
