Problem with UniqueValueRenderer

RolandoFlorez

Hi,
I have a problem with this render.
I'm trying to diferenciate the posible values from a domain field (with respective coded values). The render receive a symbol and the field. And then I'm going code value by code value (into foreach) assigning diferents color and label.
But the result is that the render is drawing all codedvalues with the last color assigned.

uniqueValRender: function () {
   var randomColor;
   var defaultSymbol = this.getBaseSymbol();
   console.info(defaultSymbol);
   console.info(this.parameters.field);
   var renderer = new UniqueValueRenderer(defaultSymbol, this.parameters.field);
   var codedValues = this.parameters.domainObject.codedValues;
   var color;

   arrayUtils.forEach(codedValues, function (value) {
      console.info(value);
      randomColor = '#' + Math.floor(Math.random() * 16777215).toString(16);
      console.warn(randomColor);
      color = new Color(randomColor);
      /*color.a = 0.5;*/
      console.info(color);
      console.info(value.code);
      console.info(value.name);
      renderer.addValue({
      value: value.code,
      symbol: defaultSymbol.setColor(color),
      label: value.name,
      description: ""
   });
   console.info(renderer);
});

   var optionsArray = [];
   var drawingOptions = new LayerDrawingOptions();
   drawingOptions.renderer = renderer;
   // set the drawing options for the relevant layer
   // optionsArray index corresponds to layer index in the map service
   optionsArray[this.parameters.idPos] = drawingOptions;
   this.parameters.layer.setLayerDrawingOptions(optionsArray);
   this.parameters.layer.show();
   if (!this.legend) {
      this.createLegend();
   }

}

You are using the same instance of symbol object "defaultSymbol" and then adding it to each of the UniqueValues. when you update the color using "defaultSymbol.setColor(color)", it updates the color for all the coded values.

Try creating different instance of symbol for each coded values, that should solve your problem.
