Hello, we've decided to move our hosted apps that were on a Windows machine using NGINX server to a Ubuntu machine. So we followed the same steps as we did on Windows; installed NGINX, moved the app files to the www folder and that's it. But upon accessing the app through a browser many things aren't loaded like icons and such, and on the console I get the error "498" on some request to esri's server. According to google 498 means invalid token but I can't think why the generated token would be invalid in a Linux. The problem is that we don't have any infrastructure specialist, we always relied on simplicity of Windows and now we are stuck in this problem. Is there any extra steps/configuration that need to be done in a Linux environment to properly use Apps created by WAB? All we installed in this machine was the NGINX server, do we need do install any windows packages or anything else? ... View more

Is it possible to have a code/function that executes before a custom on-panel widget is opened? For example I want it to hook a button in the Map's popup that will then call the widget if it's not open. A off-panel widget or external configuration wouldn't be ideal, I need this to be inside the Widget's scope and keep it modular. ... View more

This question has been answered many times before, and I know one solution is to simply change it so (Esri's)dojo is the last one to load. Problem is I'm working on a modular widget that has no access to the page's html to change the order, I must only load libraries via Dojo's AMD Loader. Folder structure : /Widget    --/Widget.js    --/Datatable.js This is the Widget.js file: define([    './Datatable',    'https://code.jquery.com/jquery-3.3.1.min.js',    'https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.bundle.js', ], function(Datatable){ ... } ‍‍‍‍‍‍ And Datatable.js (just another module I created for organization) : define([    'https://cdn.datatables.net/v/bs4/dt-1.10.18/r-2.2.2/datatables.min.js' ],function(){ ... }‍‍‍‍‍‍‍ I have two major issues here; 1) The AMD Loader is asynchronous and doesn't resolve non-AMD modules dependencies, meaning that order should be important for these libraries. datatables.min.js requires bootstrap.bundle.js that requires jquery-3.3.1.min.js So, If I'm lucky the request will load in order depending on latency, not reliable at all. 2) Both Bootstrap and Datatable generic javascript files raise a "multipleDefine" error, probably due to them trying to define "jquery", I'm really not sure how to fix this. How can I resolve these 2 problems? ... View more

So, I know the documented way to do it would be like this : const fl = new featureLayer(url); fl.on('load', () => {    doSomething(); })‍‍‍‍‍‍‍‍‍‍‍‍ But there is a problem with the approach above, if the featureLayer has already loaded between its creation and the event binding, doSomething() will never trigger. This would be solved by simply having a callback parameter on the featureLayer constructor, which doesn't. So, for now I'm using the following solution : const fl = new featureLayer(url); if(!fl.loaded){                 fl.on('load', () => {                            doSomething();                    }) }else{                    doSomething(); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ But there's also a very nasty possible error with my temporary solution, it can happen that the featureLayer will load between the if/else check, and then doSomething() will never trigger. Is there an actual solution to this? Is this a bug? Am I missing something? Here's a pen showing the issue : FeatureLayer  I'm using the setTimeout to force the layer to load, in our company the arcgis server is local so they load really fast, before binding the event as I stated above ...
