When doing a request like this:
List<FsNode> actorsList = Fs.getNodes("/domain/euscreenxl/user/david/publications/1/collection/73b2a81e-4ab7-426f-8226-224aa9d9f165/rights/1/role/owner", 2);
OR
FSList rolesFsList = FSListManager.get("/domain/euscreenxl/user/david/publications/1/collection/73b2a81e-4ab7-426f-8226-224aa9d9f165/rights/1/role/owner", false);
The retrieved nodes do not contain the referid's that are actually inside smithers.
