Use of template.fetch() for a relationship entity?

[jkranes]

The javadoc for template.fetch() seems to imply that it can be used for relationship entities as well as node entities, but when I try to use it for a relationship entity I get a ClassCastException:

org.neo4j.kernel.impl.core.RelationshipProxy cannot be cast to org.neo4j.graphdb.Node

Is fetch() supposed to work for relationship entities or is it just for node entities?

If just for node entities, is there a recommended way to force the loading of properties for a relationship entity? When I use template.findOne(relationshipId, relationshipClass), the properties of the returned relationship entity object are null, presumably because it is lazy loaded.

Thanks for any help.

Digging deeper, it seems I do not need fetch() for the relationship entity, as most of the properties are being populated, with the exception of the relationship type field (the field annotated with @RelationshipType). This field is null in the proxy object even though I initialize it in my entity class using:

@RelationshipType
RelationshipTypes type = RelationshipTypes.XXX;

I'm not sure whether this behavior is expected, but in any case I can work around this by simply changing the code in my getType() method from:

return type;

to

return RelationshipTypes.XXX;
