Hello, I use JDO and have 2 entities and want a many to many relation between them. In this relation I need an additional attribut. I've tried to create a third entity with 2 one to many relations to the others. In the documentation there is an example with a one to many relation and a key object as PK. This key is built up with the KeyFactory.Builder but there is only the opportunity of one parent. I also tried to have 2 PKs and an objectIdClass:
@PersistenceCapable(identityType = IdentityType.APPLICATION,objectIdClass = ComposedIdKey.class) But 2 PKs are not supported in GWT. Is there any possibility to model this problem in GWT?
