Neo4J Cross-store - am I missing something?

[martytime]

I've set up a cross-store entity, but keep getting an error (stacktrace below). After debugging, it appears that the jpa portion of the entity has not saved prior to the flush() operation. I'm using a spring-configured repository and assumed that the neo4j repository extension would automatically wire in a repository that knows how to save both parts of the cross-store entity.

Then I noticed in the myrestaurants-social example project that the repository for the cross-store entity (UserAccount) wires in its own EntityManager and manually performs load and persist operations. Did I assume too much? Are there plans to create a repository factory bean that would seamlessly bridge the two worlds?

Thanks,
Eric
