cannot create two unique label indices on NodeEntity [DATAGRAPH-494] #1057

Kris Zawadzki opened DATAGRAPH-494 and commented

I have two properties in my entity, both indexed with unique constraint. indexes are label-type. spring complains:

Caused by: org.springframework.data.mapping.model.MappingException: Duplicate unique property [...] Only one unique property is allowed per type at org.springframework.data.neo4j.support.mapping.Neo4jPersistentEntityImpl$1.doWithPersistentProperty(Neo4jPersistentEntityImpl.java:84)

This seems to be some old limitation that has been removed for label indices. java api works w/o problems (after removing @Index annotation) template.getGraphDatabaseService().schema().constraintFor(DynamicLabel.label("User")).assertPropertyIsUnique("nick").create();

Affects: 3.1.1 (Dijkstra SR1)

In order to give users a better vision of what’s happening on SDN, we are bulk closing several issues because they are no more relevant, or related to old and un-maintained SDN versions. We tried to keep the issues that are still relevant, like feature requests that are still absent from SDN. However, some may have been closed by error. If so, please feel free to reopen.
