Hi,
My use case is pretty simple.
I want to create a *Meeting* (represented by a node).
Each Meeting accepts several *Participation*s (Participation represented by
another node linked to Meeting) :
class Meeting ........ {
....................
@org.springframework.data.neo4j.annotation.Fetch
@org.springframework.data.neo4j.annotation.RelatedTo(`type` = "TO",
direction = Direction.INCOMING)
var participations: java.util.Set[Participation] = new util.HashSet[
Participation]
}
When a Meeting is created, participations relationship should be contain
the Meeting's creator, and an event (*Event* Node) should be also saved
having this Participation as a relationship:
class Event (......., @Fetch @RelatedTo(`type` = "CONCERNS", direction =
Direction.OUTGOING) val participation: Participation))
The issue:
*org.springframework.dao.DataRetrievalFailureException: Node 66 not found;
nested exception is org.neo4j.graphdb.NotFoundException: Node 66 not found*
I interpret SDN doing those steps:
- Want to Save Meetings, but noticed that a several relationship
*Participation*s must be created. So create those ones.
- Meeting is then saved, linked to those Participations.
- Event should be save, but noticed that it needs the creator's
Participation reference. So SDN tries to find it, but fails !
Why can't SDN find the Participation relationship since the whole is being
made inside the same transaction?
Thanks a lot,
Michael
