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

Question

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!

I wonder if this will work:

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

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        });
