unable to see nodes created layer.add()

[vvavepacket]

Hello,

Why is that when we add nodes using the layer.add(layer.getGeometryFactory...) method, it doesn't create the actual nodes in the layer? If we add a node using the following:

Node temp = graph.createNode(Road.Label1),

Below is my code,, I;m adding these linestrings in my layer, and I want to see them as nodes in the Neo4j browser but they are not coming.

	public static void ReadAndCreateNodes_Road() throws JsonParseException, JsonMappingException, IOException {
		File storeDir = new File("20170508_line");
		GraphDatabaseService graph = new GraphDatabaseFactory().newEmbeddedDatabase(storeDir);
		SpatialDatabaseService db = new SpatialDatabaseService(graph);
		EditableLayer layer = db.getOrCreateEditableLayer("line");
		// read geojson
		File fin = new File(
				"sample_roads.geojson");
		FileInputStream fis = new FileInputStream(fin);
		// Construct BufferedReader from InputStreamReader
		BufferedReader br = new BufferedReader(new InputStreamReader(fis));
		String line = null;
		int counter = 0;
		while ((line = br.readLine()) != null) {
			System.out.println(counter++);
			GeoJsonObject object = new ObjectMapper().readValue(line, GeoJsonObject.class);
			if (object instanceof Feature) {
				LineString geometry = (LineString) ((Feature) object).getGeometry();
				List<LngLatAlt> x = geometry.getCoordinates();
				try (Transaction tx = graph.beginTx()) {
					CoordinateList coordinates = new CoordinateList();
					for(int i=0;i<x.size();i++) {
						coordinates.add( new Coordinate( x.get(i).getLatitude(), x.get(i).getLongitude() ), false );
					}
					SpatialDatabaseRecord record = layer.add(layer.getGeometryFactory().createLineString(coordinates.toCoordinateArray()));
					tx.success();
				}
			}
		}
		br.close();
	}

What could have gone wrong? Thank you.
