Once you add a graphic to the FeatureLayer, the visibility/symbology is no longer managed by the Graphic, but the Layer. You can set a definitionExpression or apply a FeatureEffect. ... View more

The 4x AMD samples are deprecated as it becomes more difficult to get apps and other modern bits to play nice together. We won't be updating them. You can try updating to the latest dojo utils, with the latest closure compiler.  We have a fork with 1.17.3 here. https://github.com/Esri/dojo-util/tree/v1.17.3/esri-3.42.0 ... View more

@JS_GilbertAZ is correct. The 4x equivalent to 3x ArcGISDynamicMapServiceLayer is the MapImageLayer. It has an updated API to make it easier to configure the layers in the service. In the first screenshot, with the FeatureService, the API is going to request data in cacheable tiles, which can lead extra requests. If you are using multiple FeatureLayers to display the same layers that are in the Map Service, then that would explain the number of requests and possibly slower than expected response if they each contain a good amount of data. MapImageLayer can still perform very fast for Map Services, and if needed you can still create a FeatureLayer from a SubLayer that you an use for queries and more. ... View more

You have a second hitTest in your code there, but aren't passing the options with the target layer in the include. https://developers.arcgis.com/javascript/latest/api-reference/esri-views-MapView.html#hitTest You do it the first hitTest. I tested that in your codepen and it works just like before when you do that. This sample does something similar. https://developers.arcgis.com/javascript/latest/sample-code/view-hittest/ For your example, this works ok.  But note that hitTest was updated at 4.24. https://developers.arcgis.com/javascript/latest/release-notes/#mapview-and-sceneview-hittest-updates So depending on how you are using the hitTest results, you may need to check the type like the snippet in the docs. ...

Do you have a sample/repro in codepen maybe? Here is a sample using Sublayers with Identify https://codepen.io/odoe/pen/qBYbOyG It's important to note that you can send sublayers or layerIds, but not both. ... View more

  You could do the whole thing first too   const latLonPolygonGeometry = webMercatorUtils.webMercatorToGeographic(graphic.goemetry);   Then go over the rings. Lots of options! ... View more

Assume those are WebMercator, so you can run the polygon through the webmercatorUtils first. https://developers.arcgis.com/javascript/latest/api-reference/esri-geometry-support-webMercatorUtils.html#webMercatorToGeographic ... View more

The widget isn't extensible, so you can't add more buttons. You can use the SketchViewModel and build a custom component around that. https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Sketch-SketchViewModel.html Depending what you want it to do though, you could have a container that wraps the Sketch widget and your custom button along side each other, so it looks like a new button, but when you click it, you can call methods on the Sketch widget or the layer, not sure what your button would do. ...

This is expected. You might see some oddities because you are using a class instance to new up a new class, which you don't have to do // don't need this updatedGeometry.push(new Polygon(gra.geometry)); // can do this updatedGeometry.push(gra.geometry); // or this updatedGeometry.push(gra.geometry.clone());   But you have two polygons that do not overlap. So when they union, it becomes a polygon with multiple rings. You don't need to iterate over the rings, the result of the geometryEngine union is a geometry, so you can use it directly. const joinedPolygon = geometryEngine.union(updatedGeometry); graphicsLayer.removeAll(); let resultgraphic = new Graphic({ geometry: joinedPolygon, symbol: mergeSymbol }); graphicsLayer.add(resultgraphic); demo: https://codepen.io/odoe/pen/RwyYKxN?editors=0010   If you want the polygons to become a single polygon with a single ring, you can do something like convexHull const [result] = geometryEngine.convexHull(updatedGeometry, true); graphicsLayer.removeAll(); let resultgraphic = new Graphic({ geometry: result, symbol: mergeSymbol }); graphicsLayer.add(resultgraphic); demo: https://codepen.io/odoe/pen/ZEoMLmj ...

I thought that would have worked, but doesn't look like it. You can clone the symbol though, modify the outline and replace it. https://codepen.io/odoe/pen/zYjjOPm?editors=0010 // something like this view.on("click", async (e) => { const { results } = await view.hitTest(e); for (let result of results) { if (result.type === "graphic") { const sym = result.graphic.symbol.clone(); const idx = Math.floor(Math.random() * 10); sym.outline && (sym.outline.color = colors[ Math.floor(Math.random() * 10) ]); sym.color = colors[ Math.floor(Math.random() * 10) ]; result.graphic.symbol = sym; } } }); ...
