We're about to decide on ArcGIS API version to use. It seems that he only lacking feature for our app in version 4 is WMS/WFS support.   When ArcGIS API for Javascript 4 will support WMS/WFS ?  ... View more

I write a widget for WAB 2.1 where I add 3 Dynamic MapService Layers hosted on ArcGIS Server. Every layer has one sublayer visible at widget startup.  var layer1 = new ArcGISDynamicMapServiceLayer("http://62.236.121.188/arcgis/rest/services/DataAndMaps/Background/MapServer", {"id": "Background"}); layer1.on("load", function (e) { layer1.setVisibleLayers([2]); map.addLayer(layer1); }); var layer2 = new ArcGISDynamicMapServiceLayer("http://62.236.121.188/arcgis/rest/services/DataAndMaps/Pressures/MapServer", {"id": "Pressures"}); layer2.on("load", function (e) { layer2.setVisibleLayers([2]); map.addLayer(layer2); }); var layer3 = new ArcGISDynamicMapServiceLayer("http://62.236.121.188/arcgis/rest/services/DataAndMaps/MSP/MapServer", {"id": "MSP"}); layer3.on("load", function (e) { layer3.setVisibleLayers([2]); map.addLayer(layer3); }); When the button is clicked, visible sublayers in every layers should be changed. I want to get sublayer 2 not visible and sublayer 3 becomes visible for every layer. function onLayerListItemClick(e) { layer1.setVisibleLayers([3]); layer2.setVisibleLayers([3]); layer3.setVisibleLayers([3]); } What happens on click, is that the last (of three) layer changes visibility of sublayers as expected. First layer makes visible 14 sublayers and second - 33 sublayers.  I did the same task thing not using WAB, but just Javascript API for ArcGIS 3.18. And it work fine! Sublayers 2 become not visible and sublayers 3 become visible for every layer.   I do not understand why is this happening. Can, please, somebody from WAB team explain what is going under calling setVisibleLayers() and what I should do to make my WAB widget do the same thing that I can do with pure Javascript API. Source code WAB Widget and JSAPI versions are attached. Kind regards, Andžej ... View more

I have published a raster as Image service and want to display it on the map using Arcgis api 4.0. Color of pixel should depend on raster cell value, exactly as in this example: ImageryLayer - Set a client side pixel filter | ArcGIS API for JavaScript 4.0 Image service is published here: AISData/CONTAINER_2013_04_test (ImageServer) and it has Min Values: 0 Max Values: 421 But when I replace Image service with mine in example's source code I get values between 0 and 255. And I get 3 bands when expected to get 1 with pixel values. I guess this issue regards this example description: "Setting the rendering rule to the None raster function gives the user the ability to get the actual value of the pixel (the sea temperature) without it being altered by another raster function or rendering rule." I also guess that None raster function is not available in my Image service, because I receive javascript Error: ImageLayerView2D.js:6 Error: {"error":{"code":400,"message":"Unable to complete operation.","details":["Do not allow execution of client function."]}}     at Error (native)     at .<anonymous> (http://js.arcgis.com/4.0/esri/layers/support/Raster.js:6:218)     at f (https://js.arcgis.com/4.0/init.js:150:21)     at p (https://js.arcgis.com/4.0/init.js:149:331)     at resolve.callback (https://js.arcgis.com/4.0/init.js:151:151)     at https://js.arcgis.com/4.0/init.js:325:198     at e (https://js.arcgis.com/4.0/init.js:153:423)     at f (https://js.arcgis.com/4.0/init.js:153:349)     at b.resolve (https://js.arcgis.com/4.0/init.js:155:406)     at c (https://js.arcgis.com/4.0/init.js:154:287) How can I solve this issue? ...
