Receiving undefined is not a function when I try to implement the Measurement example

ChrisSergent — Wed, 19 Nov 2014 22:01:29 GMT

I tried create the measurement tool based on our web services and I receive the following error message: Uncaught TypeError: undefined is not a function for line 127

What is causing that? Here is my code:

Your operationalLayer is an ArcGISDynamicMapServiceLayer and this object does not have a setRenderer() method. You should use the setLayerDrawingOptions() method instead:

require([
  "esri/layers/LayerDrawingOptions", "esri/renderers/SimpleRenderer", ...
], function(LayerDrawingOptions, SimpleRenderer, ... ) {
    var layerDrawingOptions = [];
    var layerDrawingOption = new LayerDrawingOptions();
    var sfs = new SimpleFillSymbol( 
                    "solid", 
                    new SimpleLineSymbol("solid", new Color([195, 176, 23]), 2), 
                    null 
                    );

    layerDrawingOption.renderer = new SimpleRenderer(sfs);

    // change 1 to the layer index that you want to modify:
    layerDrawingOptions[1] = layerDrawingOption;

    dynamicData.setLayerDrawingOptions(layerDrawingOptions);
    ...
});

There is a syntax error on the line that is throwing the error. However, you don't need to wrap the layer drawing options code in a function - my example was just taken from the ESRI documentation.

    // start measurement tool - the current layer we are measuring is the operational layer
    // error follows this line
    // function (LayerDrawingOptions, SimpleRenderer) {  <-- Remove this line
    var layerDrawingOptions = [];
    var layerDrawingOption = new LayerDrawingOptions();
    var sfs = new SimpleFillSymbol(
         "solid",
         new SimpleLineSymbol("solid", new Color([195, 176, 23]), 2),
         null
    );
    // } <-- Remove function closure

    layerDrawingOption.renderer = new SimpleRenderer(sfs);

    // The dynamicData object does not exist in your code - it is from the ESRI sample:
    //dynamicData.setLayerDrawingOptions(layerDrawingOptions);
    operationalLayer.setLayerDrawingOptions(layerDrawingOptions);

There still appear to be some issues with the measure functionality.

Your updated code worked. I just needed to move my dojo require statements above the dijits to line up with the declarations in the function.
