Relationships are not persisted when saving DTO objects as domain objects.

[scj7t4]

Hello-

I am not sure this is a bug or if I'm not understanding/using projections correctly, so I do apologize if this is the expected behavior, but the docs are not clear if it is or not.

I am using:

SDN 6.2.1
Java 11.0.14

Reproduction:

Reproduction can be found here: in this repository, specifically this test

I have a CityModel which has several relationships to PersonModel objects. The city has a MAYOR, CITIZENS, and EMPLOYEE relations to people. I create a CityModel and PersonModel and persist them to the database. I then try to load the city Model as a projection (CityModelDTO) and connect it to a PersonModel by creating a PersonModelDTO instance and setting the id to match the previously persisted PersonModel. I then save CityModelDTO via Neo4jTemplate. If I then reload it as a CityModel none of the relationships I tried to save are present. Additionally the @Property("exotic.property") property is not updated as expected.

It is not in my reproduction, but I also tried to have a PersonModelRepository that could load the PersonModelDTO in case there was any secret sauce in the loaded DTO to help make the connection but got the same result.

What I expect to happen:

Persisting the DTO should create relationships to the existing nodes or create them with the projection properties if they do not exist. If this is not the intended behavior, I would expect to see warnings / errors in the console that the relationships will not be persisted.

What does happen:

No warnings or errors in the console but the relationships / property change are not persisted.

Thank you for your work on SDN :)

Could you please give the latest snapshot builds a try? This should be fixed #2371
however it might not work with dots in the (graph) properties.

Hi, same here: Thanks for the excellent report, a fix is on its way from 6.1 on upwards.
