ChildNodeEntry previous = findPrevious(
                            index.getNodeState(), node.getNodeState());
                    LOG.debug("previous: {}", previous);
                    // (2) find the next element
                    String next = node.getString(NEXT); 
                    if (next == null) {
                        next = "";
                    }
                    // (3) re-link the previous to the next
                    index.getChildNode(previous.getName()).setProperty(NEXT, next); // <-- NPE if previous is null
