Cannot call method 'trim' of undefined when trying to draw a graphic on the map

ChristianDebono — Thu, 13 Mar 2014 07:38:52 GMT

I am trying to add a free hand polygon to my map, but it is giving me the error "Cannot call method 'trim' of undefined". Have followed the samples but still no luck on getting it working. The code can be found below.

 function initSelectToolbar(event) {               selectionToolbar = new Draw(event.map);               var selectQuery = new Query();                on(selectionToolbar, "DrawEnd", function (geometry) {                   selectionToolbar.deactivate();                   selectQuery.geometry = geometry;                   featureLayer.selectFeatures(selectQuery,               FeatureLayer.SELECTION_NEW);                    var symbol;                   selectionToolbar.deactivate();                   map.showZoomSlider();                   symbol = new SimpleFillSymbol("none", new SimpleLineSymbol("dashdot", new Color([255, 0, 0]), 2), new Color([255, 255, 0, 0.25]));                   alert(geometry.type);                   var graphic = new Graphic(geometry, symbol);                   map.graphics.add(graphic);               });                         }

Thanks for the help.

i took the liberty of mashing up your own code with the original sample to show the tool getting invoked automatically when the page loads. hope it helps
