How do I programmatically create freehand polylines?

I tried following what was done in this thread.

Here is my code:

var templatePicker = new esri.dijit.editing.TemplatePicker({           featureLayers: templateLayers,           rows: 'auto',           columns: 'auto',           style:'height:98%;width:98%;'         },'templatePickerDiv');                  templatePicker.startup();         var settings = {           templatePicker: templatePicker,           map: map,           layerInfos:layers,           toolbarVisible: false,           createOptions: {             polygonDrawTools:[esri.dijit.editing.Editor.CREATE_TOOL_FREEHAND_POLYGON],            polylineDrawTools:[esri.dijit.editing.Editor.CREATE_TOOL_FREEHAND_POLYLINE]             }         }            on(templatePicker, "SelectionChange", function() {    selectedTemplate = templatePicker.getSelected();    if (selectedTemplate) {     switch (selectedTemplate.featureLayer.geometryType) {      case "esriGeometryPoint":      alert("point");       drawToolbar.activate(esri.toolbars.Draw.POINT);       break;      case "esriGeometryPolyline":       alert("line");       selectedTemplate.template.drawingTool === 'esriFeatureEditToolFreehand';       break;      case "esriGeometryPolygon":       selectedTemplate.template.drawingTool === 'esriFeatureEditToolFreehand' ? drawToolbar.activate(esri.toolbars.Draw.FREEHAND_POLYGON) : drawToolbar.activate(esri.toolbars.Draw.POLYGON);       break;     }    }   });

The alert fires, which tells me I'm getting to the right place, but the line still uses the traditional draw.

This example is supposed to draw freehand, but it doesn't work for me either. Does it work for you?

I think you have too many equal signs. 3 === is the match type and value operator. You're trying to set the drawing tool to a value.

Try:

selectedTemplate.template.drawingTool = 'esriFeatureEditToolFreehand';

Thanks Ben! That did the trick.

I copied that code from the Esri example. I wonder why there are three ='s in that example. Maybe that is why it doesn't work in that example. Either way, you helped me.

Thanks again!
