AbstractJcrNode.location.getUuid() Returns Null for Referenceable Nodes
-----------------------------------------------------------------------

                 Key: DNA-539
                 URL: https://jira.jboss.org/jira/browse/DNA-539
             Project: DNA
          Issue Type: Feature Request
          Components: JCR
    Affects Versions: 0.6
            Reporter: Brian Carothers
            Priority: Trivial


For non-referenceable nodes, AbstractJcrNode.location.getUuid() returns the node's UUID if the node has a UUID (which is really a function of which connector the node maps to).  For referenceable nodes, AbstractJcrNode.location.getUuid() returns null but AbstractJcrNode.location.getIdProperty(JcrLexicon.UUID) returns a non-null value.

Put another way:
AbstractJcrNode.location has dna:uuid but not jcr:uuid if the node is not referenceable.
AbstractJcrNode.location has jcr:uuid but not dna:uuid if the node is referenceable

This means that the only safe way to get the corresponding UUID for a node (if one exists) is to run a code snippet like this:

        if (location.getUuid() != null) return location.getUuid();

        org.jboss.dna.graph.property.Property uuidProp = location.getIdProperty(JcrLexicon.UUID);
        if (uuidProp == null) return null;

        return this.cache.factories().getUuidFactory().create(uuidProp.getFirstValue());

It would be nice if referenceable nodes still have dna:uuid set in their location field.
