Hello, We noticed a very high CPU utilization of our WebApp built with ESRI JS API 3.26 even when non interacting with it. Digging into it, it turns out that we included a custom widget which is an iframe application built with React Nativ making "window.parent.postMessage" call to talk to our WebApp in order to send some information. The problem is that the "esri/geometry/geometryenginewebworker.js" listens to this message as well and do a switch case according to the message sent (case "equals", "disjoint", "within", ...). Of course, as it is not concerned by this message, it goes to the default case which itself post another message "Unrecognised Action" and there we go, we run into infiinite loop : Can it be fixed please ? Any worker around that come to your mind ? Here is a code pen illustrating the problem: https://codepen.io/anon/pen/zMELJK If you remove the postMessage section from the codepen ("window.parent.postMessage("Hello",window.location.origin))", you should see your CPU calming down.

Using ArcGIS JS API 4.8, when I load a webmap and configure a second basemap from a portalItem webmap, I noticed that the thumbnail of the second basemap is not displayed at startup. You need to toogle it once: Demo Using a webpack build, I even do not get the main webmap displayed at start up. I need to toogle several times the widget so that thumbnails get loaded. Any idea ? Thanks ! ... View more

Playing with the following sample, loading a webMap from a PortalItem id: Load a basic WebMap | ArcGIS API for JavaScript 4.7  I noticed that a WebMap containing a MapService with custom layers visibility defined in AGOL (overwriting thus the default ones from the service) are not respected using arcgis js api 4.7. Layers visibility configuration is the one of the service and not the one of webmap. I know WebMap is partially supported: WebMap | API Reference | ArcGIS API for JavaScript 4.7  but even with a map service that has dynamic layers enabled, it is still not respected.    Is it a temporary limitation ? Maybe linked to AGOL ?    Cheers   Nicolas ... View more
