We've designated some @ManyToOne fields as FetchType.LAZY, but we're still finding lots of Cypher queries against the db that seem to be resolving the associated entity. E.g.:

Code:
MATCH (owner:ENTITY:`MY_ENTITY_TYPE` {dbId: {0}}) -[r:parent]-> (target) RETURN target


Is this expected?

It doesn't seem to load the rest of the associated entity though - i.e. there are no queries for its embedded fields or anything.

We're using the 5.0.1 Final OGM.

Sorry for the late reply,

*-to-one entities are always resolved unless they are not nullable.

Just to be sure, could you show an example of entity mapping, the result you are seeing and the one you expect?

Thanks,
Davide

Okay, thinking about it I guess it needs to know whether to create a stub or leave the field null in the nullable case. So that makes sense to me.
