I have a 3D sceneView application that uses a work-around print function that creates a 2D map in the background from the same 'map' as the sceneView, and prints from that. This post explains the process: here. After switching to 4.6, having any feature layers or mapService layers turned to 'visible' in the sceneview, and thus the map view, causes the execute print task to fail. It doesn't throw any error in the console, just the error callback function. If I revert back to 4.5, with no changes in the code, it works perfectly.  Just wanted to throw this out there if anyone else has noticed issues around printing in 4.6. Cheers ... View more

I have a bit of code in a 3D SceneView for a draw-line tool that has worked fine until the 4.6 release. It basically grabs the map point when the user clicks on the map, and creates a line starting at that point, and adds each subsequently clicked point to the 'paths' property of the line until the user double clicks to end the process. The line is added to the map as a graphic.  After 4.6, however, I can't get the polyline.insertPoint() function to work, or any of the polyline functions for that matter. I threw together a jsbin that illustrates a similar problem: here. You have to open dev tools to see the results. I used the getPoint() function to keep it a bit simpler, but it throws an error that line.getPoint() is not a function (getPoint() documentation).  tldr: polyline.insertPoint(path index, point index, point) is not adding anything to the 'paths' property of the line I pass in Any ideas whats going on here? Am I missing something? Any help is much appreciated. Cheers ... View more

Im trying to refresh an ArcServer token in the JS API, but can't seem to figure it out. This gist is: I want to refresh the server token every hour automatically without requiring more input from the user while within the same session (ie. the user hasn't closed the browser window). Right now I get the token with a basic POST request to the server and then register that token with the ID manager like this: IdentityManager.registerToken({    server: "//exampleUrl/server/rest/services/",    token: localStorage.getItem('token') });‍‍‍‍‍‍‍‍ That's it and it works just fine, but when the token expires in an hour (which we want), I don't have a way to simply refresh the token. Since I'm not storing the password like I am the username, I can't simply fire the POST request again to generate a new token. I've looked at creating a credential object which has a refreshToken() method, but can't get it to work, and to be honest I don't fully understand the credential class as it relates to the ID manager, serverInfos, and authentication in general. I tried replacing the above code to register the token with ID manager with the following code with no success: var serverInfo = new ServerInfo(); serverInfo.server = "//exampleUrl/server1"; serverInfo.tokenServiceUrl = "exmapleUrl/rest/generateToken"; let idObject = {serverInfos: [serverInfo]}; let credential = {    server: "exampleUrl/server1/",    ssl: true,    token: localStorage.getItem("token"),    userId: localStorage.getItem("username") } idObject.credentials = [credential]; IdentityManager.initialize(idObject);‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ (used this as a guide, but I'm not sure Jeff Pace was using the 4.x API) Does anyone have any examples of using the refreshToken() method, or any insight into the best way to accomplish an automatic token refresh within the API? ...

I noticed a problem with the calculated centroid of a polygon graphic when you draw a very small polygon. I am trying to add a text graphic to the center of a polygon graphic by grabbing the centroid of the polygon when drawing is complete and creating a simple text symbol with the centroid geometry. The polygonGraphic.geometry.centroid.x (and y) property works perfectly when the polygons cover multiple acres, but the smaller they get, the farther outside the polygon the text labels appear. I put together an example of the problem for reference here: JS Bin - Collaborative JavaScript Debugging  *note: you must draw polygons in the clockwise direction* I've also attached a screen grab of the problem. If you zoom in a lot and draw a polygon that is 0 acres, you should notice that the text showing its area is drawn far outside the bounds of the polygon. As far as I can tell this is not a spatial reference issue. The only fix I've found it to use the polygonGraphic.geometry.extent.center.x property instead of the centroid, which works but is not ideal. I know this is kind of a niche problem, but any insight would be much appreciated. Thanks ... View more
