Hi all, I'm having a very difficult time working with embedded entities in Cassandra. Specifically, this is the case where I'm getting very strange behavior. Em = Entity Manager.
em created em begin transaction em load User entity , the embedded Address object is correct. em complete transaction User entity is now detached. Address is updated em begin transaction User is attached, and address is as well em.save(User) is invoked em flush em commit transaction The Address now has a null entity manager, and all fields are null, however it is correct when the entity was passed to the flush operation before using StateManager.get(fieldId) to retrieve the embedded object. For the Cassandra plugin in it's first implementation, we're requiring all @Embeddable entities to also implement Serializable. The embedded entity value is simply serialized to a column Here is the embedded column implementation I have created for @Embedded https://github.com/riptano/hector-jpa/blob/master/src/main/java/com/datastax/hectorjpa/meta/embed/EmbeddedColumnField.java Here is the implementation for @ElementCollection where the elements in the collection are @Embeddable https://github.com/riptano/hector-jpa/blob/master/src/main/java/com/datastax/hectorjpa/meta/embed/EmbeddedableCollectionColumnField.java Any guidance would be greatly appreciated. I know I'm not wiring the entity manager correctly during load, I'm just unsure what else I need to do. I've looked at both ElementEmbedValueHandler and EmbedFieldStrategy, however I'm not getting anywhere. Any help would be greatly appreciated. Thanks in advance! Todd
