Hi Community,
I am trying to modify the unique value renderer of a hosted feature layer. I do not get any error on executing save() operation of the layer but the unique value renderer of the layer changes in simple renderer (default renderer of feature layer).
I have attached my JS code below. Kindly let me know what I must be doing wrong.
import FeatureLayer from "@arcgis/core/layers/FeatureLayer.js";
import UniqueValueRenderer from "@arcgis/core/renderers/UniqueValueRenderer.js";
const layer = new FeatureLayer({
portalItem: {
id: ""//Hosted Feature Layer id.
}
});
const tempRenderer = layer.renderer.clone().toJSON();
const UniqueValueInfoTemp = {
label: "",//label of name
symbol: newSymbol, //Picture Maker symbol
value: "" //same as label
};
const uniqueValueGroup = tempRenderer.uniqueValueGroups[0].classes;
const newClass = {
label: "",//label of name
symbol: newSymbol, //Picture Maker symbol
value: "" //same as label
};
uniqueValueGroup.push(newClass);
uniqueValueInfos.push(UniqueValueInfoTemp);
const renderer = UniqueValueRenderer.fromJSON(tempRenderer);
layer.renderer = tempRenderer;
layer.refresh();
await layer.save();
Regards,
Mani
