Snapping doen't work in Measure tool

[KirtikaChauhan]

Hi,

I am trying to give my own feature layer in layerinfo of Measure tool. But it doesn't snap to points. I have point features in my map service, and I want to snap to features. Snapping works but it wouldn't snap to points rather it would snap to basemap.

Sample code:
esriConfig.defaults.geometryService = new GeometryService("MyGeometryServiceURL");

        map = new Map("map", {
            basemap: "topo",
            center: [-0.114, 51.8],
            zoom: 11
        });
        var dynlayer1 = new esri.layers.ArcGISDynamicMapServiceLayer("MyServiceURL");
        map.addLayer(dynlayer1);
        var sfs = new SimpleFillSymbol(SimpleFillSymbol.STYLE_SOLID,
         new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID,
         new Color([195, 176, 23]), 2), null);

        var parcelsLayer = new FeatureLayer("MyServiceURL", {
            mode: FeatureLayer.MODE_ONDEMAND,
            outFields: ["*"]
        });
        parcelsLayer.setRenderer(new SimpleRenderer(sfs));
        map.addLayers([parcelsLayer]);

        //dojo.keys.copyKey maps to CTRL on windows and Cmd on Mac., but has wrong code for Chrome on Mac
        var snapManager = map.enableSnapping({
        tolerance:0,
            snapKey: has("mac") ? keys.META : keys.CTRL
        });
        var layerInfos = [{ layer: parcelsLayer, snapToPoint: true}];
        snapManager.setLayerInfos(layerInfos);

        var measurement = new Measurement({
            map: map
        }, dom.byId("measurementDiv"));
        measurement.startup();

I am just wondering is there any limitation on snapping that it does only for grid's and not for point.

Any help would be really appreciated.

Works with Feature layer, wasn't working because I had forgotten to give the id of feature layers and was adding a group layer.
