Taylor Jeppe,

I have thought about this…it’s the end goal, and would be the result of implementing JPA, which requires this behavior, but it does raise the bar a tad. once jo4neo is 1.0, dependable and well tested we’ll take that step.

I was wondering - have you considered implementing something like a PersistenceContext from Hibernate, where you within a transaction is guaranteed to get the same instance back every time you query/navigate to the an instance already loaded in the graph? Like if I fetch a list of objects under my root and later, in the same transaction, query for the same objects using find() - I would assume performance would be better (?) if jo4neo cached the beans, so identical object were the same instance (so == would work on them) ? /Jeppe Very cool – jo4neo is shaping up very nice.
