lang.clone === error? when copying esri graphic

[JerryGarcia]

I get the following error when trying to clone a grahic:

Uncaught TypeError: Cannot read property 'path' of null

If I cannot use Dojo lang.clone to copy a graphic, then can someone provide some sample code to do this?

I need to make a copy of a graphic, change it's name attribute, and add it to a FeatureLayer.

Thanks!

What is your code for cloning the graphic? This example seems to work properly, which slightly modifies the "Add graphics to a map" sample.

var graphic = new Graphic(evt.geometry, symbol);
var clone = lang.clone(graphic);
map.graphics.add(clone);

I get the error with this code:

var g = this.polylineGraphics.graphics[0];

var clone = lang.clone(g);

...

where as polylineGraphics:

	this.polylineGraphics = new FeatureLayer({
	layerDefinition: {
	geometryType: 'esriGeometrypolyline',
	fields: [{
	name: 'OBJECTID',
	type: 'esriFieldTypeOID',
	alias: 'OBJECTID',
	domain: null,
	editable: false,
	nullable: false
	}, {
	name: 'name',
	type: 'esriFieldTypeString',
	alias: 'name',
	domain: null,
	editable: true,
	nullable: false
	}]
	},
	featureSet: null
	}, {
	id: 'polylineGraphics',
	title: 'polylineGraphics',
	mode: FeatureLayer.MODE_SNAPSHOT
	});

I wonder if this will work:

var clonedGraphic = new Graphic(sourceGraphic.toJson()):

This worked for me. Thanks.
