Using a Renderer to override the symbology coming from the map service

MichelTurmel — Fri, 09 Oct 2020 17:52:02 GMT

I am in the process of creating my first custom 2 D widget and I can dynamically add a layer on the map , but as soon as I try to add a renderer to override the symbology coming from the map service then the layer does not show on the Layer List anymore and I get no error message

Here is my environment:

- Portal for ArcGIS version 10.6

- Web AppBuilder Developer Edition 2.6

- ArcGIS JavaScript API 3.33

Here is part of my code: as soon as I had the lines in bold then the layer does not show anymore:

I have defined:

define(['dojo/_base/declare',

'jimu/BaseWidget',

'dojo/on',

'esri/layers/FeatureLayer',

'esri/renderers/SimpleRenderer',

'esri/symbols/PictureFillSymbol',

'esri/Color',

'esri/map',

'esri/dijit/Legend'

function(declare,

BaseWidget,

on,

FeatureLayer,

SimpleRenderer,

SimpleFillSymbol,

Color,

Map)

{

//To create a widget, you need to derive from BaseWidget.

return declare([BaseWidget],

{

baseClass: "test",

..........

_onBtnTestClicked: function()

{

var comp1 = test1.value;

var template = new esri.InfoTemplate();

var comp1OperatorLayerURL = "https://........";

var comp1OperatorfeatureLayer = new esri.layers.FeatureLayer(comp1OperatorLayerURL, {

id: comp1Operator,

outFields: ["*"],

opacity: 0.5,

infoTemplate: template,

mode: esri.layers.FeatureLayer.MODE_SNAPSHOT,

definitionExpression: comp1OperatorSearch

});

comp1OperatorfeatureLayer._titleForLegend=comp1OperatorfeatureLayer.title=comp1OperatorfeatureLayer.name=comp1Operator;

// set the symbology

var symbol = new esri.symbol.SimpleFillSymbol().setColor(new esri.Color([255,0,0,0.5]));

var renderer = new SimpleRenderer(symbol);

comp1OperatorfeatureLayer.setRenderer(renderer);

......

map.addLayers([comp12NonOperatedOVOperatedfeatureLayer,...]);

......
