This appears to be app specific. 2D and 3D handle resolving the layerView slightly differently. The app appears to work for 2D because the layerView is resolved before the StreamLayer is connected. In the `whenLayerView` block, the `connectionStatus` is initially disconnected. The watcher later fires when the status changes to `connected`. For 3D, this isn't the case so the watcher never fires. This means that the `processConnect` function is never invoked. The application shouldn't assume that the initial state of the `connectionStatus` is `disconnected`. In the `mapView.whenLayerView(layerView)` block you first need to check what the `connectionStatus` is currently set to, e.g.: mapView.whenLayerView(streamLayer).then(function(layerView) { streamLayerView = layerView; if (layerView.connectionStatus === "connected") { processConnect(); } layerView.watch("connectionStatus", function(value) { ... } If you call `streamLayerView.disconnect()`, the watcher event does get fired.
