Spring-data-neo4j + @Query throws PropertyReferenceException

Question

I have following repository for my Domain class:

public interface IDomainRepository extends GraphRepository<Domain>, RelationshipOperationsRepository<Domain>{
    //cause of error
    @Query("MATCH n WHERE id(n) = {0} SET n :{1}")
    public void attachLabel(Long id, String label);

}

From GraphManager (a service, which is using IDomainRepository) i'm calling attachLabel as following:

@Transactional
    public void attachLabel(Domain domain, String label){
        domainRepository.attachLabel(domain.getId(), label);
    }

And here is my test case, for attachLabel method:

@Test
    public void attachLabelSuccess(){

        Domain domain = new Domain();
        domain.setName(UUID.randomUUID().toString());
        domain.setDescription("xyz");

        domain = graphManager.create(domain);
        graphManager.attachLabel(domain, "DummyLabel");

        Domain d1 = domainRepository.findOne(domain.getId());

        //Should have [Domain, DummyLabel]
        Assert.assertEquals(2, d1.getLabels().size());
    }

I get the following exception, when I run the test it fails at loading ApplicationContext:

Caused by: org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'IDomainRepository': 
Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: 
No property attach found for type Domain!
...
Caused by: org.springframework.data.mapping.PropertyReferenceException:

at org.springframework.data.mapping.PropertyPath.from(PropertyPath.java:270)
at org.springframework.data.mapping.PropertyPath.from(PropertyPath.java:241)

Seems that SDN is somehow trying to map first part of attachLabel (attach) to property of Domain class. I've tried to rename the method, but the error still appears.

Configuration: Sprind-Data-Neo4j version 3.1.1.RELEASE, neo4j version 2.1.2.

FIXED The problem was, that I accidentally used @Query annotation from mongodb namespace instead od neo4j.

You can't update labels with parameters in Cypher. That's unfortunately not possible.

So you'd have to construct the query and run it via the neo4jTemplate.

Yes, I noticed that and already solved it in the same way you suggested. I also noticed that there is @Labels annotation (planned) for managing labels. When is it going to be supported?
