Cannot add new relationships when using @RelationshipProperties #2599
Description
SDN will not save relationships annotated with @RelationshipProperties if the start node already exists.
Please see this example app that reproduces the bug.
For example, say you have a schema like this, where two nodes are related and this is represented by a
class annotated with @RelationshipProperties
@Node
public class Cat {
@Relationship("HAS_CLAW") List<HasClaw> claws;
}
@Node
public class Claw {
}
@RelationshipProperties
public class HasClaw {
@Id @GeneratedValue Long id;
boolean dewclaw;
@TargetNode Claw claw;
}
Once you create a Cat, you can no longer add new HAS_CLAWS relationships
Cat cat = new Cat();
cat.getClaws().add(new HasClaw(false, new Claw()));
catRepository.save(cat);
cat.getClaws().add(new HasClaw(true, new Claw()));
catRepository.save(cat);
Cat found = catRepository.findById(cat.getId()).get();
assertThat(found.getClaws()).hasSize(2); // fails: size is 1
Note that relationships not annotated with @RelationshipProperties (for example the Dog entity in the example code)
are not affected by this.
This example worked correctly in SDN 6.3.2, but it fails with SDN 6.3.3.
