Update entity with relationship through PUT and link-property [DATAREST-1062]

Michael Igler opened DATAREST-1062 and commented

Please consider the following code:
...

@NodeEntity
public class MessageCode extends ... {

    @Relationship
    private Product product;
    ...
}

Product is also annotated with @NodeEntity.

I used to update the product through a PUT-request ("application/hal+json") to "http://localhost:2600/api/messageCodes/12" with the JSON-content like this in JPA projects:

{   ...
    "product": "http://localhost:2600/api/products/10"
    ... some more properties
}

This does not work in a new spring-data-neo4j project I recently created and I wonder why. Doing a PUT to the relationship ".../api/messageCodes/12/product" works. The corresponding curl-request would be:

curl -v -X PUT -H "Content-Type: text/uri-list" -d "http://localhost:2600/api/products/10" http://localhost:2600/api/messageCodes/12/product

So the questions is: Is there any difference between a JPA-project and a Neo4J-project considering this update-scenario through REST?
