JS API 4.17 layerView.queryExtent is incorrect?

Tim_McGinnes — Sun, 12 Dec 2021 02:32:34 GMT

I am having some issues when doing a layerView.queryExtent in 4.17 - it is always returning 0,0 for xmin,ymin. If you simply change the JS API back to 4.16 it works fine. I am using EPSG:7856 for basemap and featurelayer if that makes any difference.

4.17 Console:

XMin: 0, YMin: 0, XMax: 496267.40614137735, YMax: 7044933.36744386

4.16 Console:

XMin: 484190.3556723228, YMin: 7034270.401998081, XMax: 496267.40614137735, YMax: 7044933.36744386

<script src="https://js.arcgis.com/4.17/"></script>
<script>
require(["esri/WebMap","esri/views/MapView","esri/layers/FeatureLayer"], function (WebMap, MapView, FeatureLayer) {
  const map = new WebMap({portalItem: {id:"997b15031351498d9266a664f7843a8a"}});
  const featureLayer = new FeatureLayer({url:"https://services3.arcgis.com/NvTosUQn3ZE5keno/arcgis/rest/services/big_data_test/FeatureServer/0",outFields: ["*"]});
  map.add(featureLayer);
  const view = new MapView({container: "viewDiv",map: map,popup: {dockEnabled: true,dockOptions: {breakpoint: false}}});
  view.when(function () {
    view.whenLayerView(featureLayer).then(function (layerView) {
      layerView.watch("updating", function(val) {
        if (!val) {
          layerView.queryExtent().then(function(response) {
            console.log("XMin: " + response.extent.xmin + "," + "  YMin: " + response.extent.ymin + "," + "  XMax: " + response.extent.xmax + "," + "  YMax: " + response.extent.ymax)
          });
        }
      });
    });
  });
});
</script>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi there,

This issue will be fixed at the JS API version 4.18. It is planned to be released end of December. You can test the fix using the `next` version of the api sometime next week.
