Hi Mark, Would you give some details background of the specific "layer A"? I think there must be some reasons for it does not show in configure dialog of Attribute Table widget. However, we cannot give you any further suggestions unless we know the details of your "layer A", such as what's data source of it? Where it redirects to when you click the "description" in the context menu of Layer list widget? A map service layer or feature service layer? Is it secured? Or it's an csv layer? Can it be shown in the table of ArcGIS Online mapviewer? etc. ... View more

Hi Lefteris, Have you tried the Query Widget? I think you can filter a layer in Query Widget UI and also in the configuration json file. Query widget—Web AppBuilder for ArcGIS | ArcGIS Query—Web AppBuilder for ArcGIS (Developer Edition) | ArcGIS for Developers ... View more

Hi Alex, Registering an app in ArcGIS Online or Portal is mainly for oAuth2 authentication purpose, as soon as you got the Client ID and Client Secret, you have to exchange a valid token for your private resources by yourself. ArcGIS Online Authentication | ArcGIS for Developers How the "proxy" part in config.json file works can be found here: Use proxy—Web AppBuilder for ArcGIS | ArcGIS. For your scenario, I think you have to write some server code in your proxy file to identify the requests to private resources and append valid token (it's your responsibility to get a valid token, also needs server code)  to those requests at least. In "proxy" part of config.json file, you may want to set some rules to reduce the unnecessary request passing to your proxy. Hope this helps. ... View more

Hi Alex, The reason why you can see the agol popup(oAuth2 authentication dialog indeed) is because your webmap or some layers in the webmap is not shared to public. Otherwise no authentication dialog will appear. To remove the oAuth2 authentication dialog, it means on every request to private resources in your deployed app(private webmap or private layers in webmap) have to come along with a valid token. This can be done by putting a proxy which has valid token in it  in front of your deployed app, as long as the end users visit the deployed app through the proxy(indeed end users will not know the real url of the app), then no security challenge will occur to end user. To achieve your goals, you need do following things: In your proxy file, write server code to process all requests to the private resources. Specifically, identify all requests that need token, and concatenate valid token to those requests. In your proxy file, write server code to refresh the token if it’s expired. Put your own IIS security challenge before the proxy, which also needs some code. By the way, you've mentioned proxy.config and <ProxyConfig> tags, I assume you're using the sample proxy file from esri’s github. This proxy file is just too simple for you to achieve above goals, more server code is needed. ... View more

Thanks. ... View more

When you start nodejs manually like above, then you can leave the startup.bat batch file away. So when you execute "node_x86.exe server.js -port=80" and got " Server listening http connection on port 80 in development mode Server listening https connection on port 443 in development mode " message, then you can enter "http://yourmachinename/webappbuilder" in the browser now to open Web AppBuilder. Just try this to see if your can log into your Portal when nodejs running on port 80. Thanks. ... View more
