Diego, I am happy to post on any solutions that I find, thank you! In response to your question: Esri advised me to add the token to the JSON request once it reaches the proxy, not before. They also informed me would be very difficult to add the token at the client side as, if you are using a proxy, the token is stored on the proxy server, not in the client side app. Because for this, the Esri print widget guys at the UC advised me to work with our development staff to add a custom modification onto the C# proxy (available on GitHub) that we are using. Here is the link if you don't already have it: GitHub - Esri/resource-proxy: Proxy files for DotNet, Java and PHP. I have used Esri premium content in maps before, in order to circumvent the need for the end user to authenticate, I have used Esri's Hosted Proxies​. To use them, just add the layer to your ArcGIS Online content and opt to store credentials with the premium content layer. Be advised: If you do this with any service or layer that uses credits, the credentials that you enter will be charged. I have successfully printed using the ArcGIS Online print utility tool with that layer on the map. ArcGIS Online Print Utility: Task: Export Web Map Task Sorry I could not be of more assistance, if I get any more updates I will pass them along. Just as a side note, Esri advised to avoid adding custom functionality directly into the current Print widget as in the future, the print services will be revamped to allow for templates created using ArcGIS Pro.

Yue, Will the Bing maps still show if a proxy is used on the WAB app? Thanks! Chris ... View more

Hello all, Another Update: I kept looking into this problem and I found our why the Esri proxy will not work with printing secured services. Here is what I found: ========================================================================================== Post by: Artemis Fili The resource proxy will not print a secured map service. This is by design. So it is possible to use the proxy in order to authenticate and display the secured service on the map, but when it comes to printing a secured service, the resource proxy will not handle this scenario as it will not pass the token in the Web_Map_as_JSON parameter. If you are using a short lived token, then a solution would be to let the identity manager handle the authentication for you, meaning that you will get a prompt to enter your credentials once the app loads and then these credentials will be used when you try to print. Otherwise, you can create a custom print service and embed the credentials as described in the article. If you choose to use the second option, please make sure that you use a 10.3 print service or above as there was an issue in the earlier versions which is fixed in 10.3 Link: PrintTask, Secure AGS Service, and Resource Proxy ========================================================================================== Chris ...

Artemis, What if you are trying to generate a print that includes secured feature services that are hosted on ArcGIS Online? We have created an app that is embedded in a website. In order to bypass the need to log in to ArcGIS Online whenever the app is opened, we have utilized the proxy. We would like to include Esri's print functionality into the app. But with the proxy utilized, the print requests fail as the Esri Print Service does not have permissions to access the layers. Thanks! Chris ... View more

Here is what Esri's site says about secured OGC Layers. Secure OGC services OGC WMS and WMTS services secured with web-tier authentication, such as Integrated Windows Authentication (IWA), a public key infrastructure (PKI), Basic, or Digest access authentication, are supported. OGC WMS and WMTS services secured with token-based authentication are not supported. Configure support for OGC services secured with web-tier authentication by adding the server hosting the services to your organization’s list of trusted servers. The server must support CORS; otherwise, layers hosted on the server will not function as expected in ArcGIS Online. If you will access the secure OGC service with Internet Explorer, you may need to add the domain of your organization’s trusted servers to your browser’s trusted sites list. Once the server has been added to the list of trusted servers, you can add your OGC services to the map viewer or as an item (WMS only). If authentication is necessary, users adding or viewing secured OGC layers will be prompted to enter their credentials. Link: OGC—ArcGIS Online Help | ArcGIS Hope this helps! Chris ... View more

Frank, Currently, the ability to enter time data in the "Out of the Box" Edit widget is not available. If you have the WAB Developer Edition, you can download the app and edit the widget's code to show the time field. Esri is planning on fixing this for the UC Release. Here is the thread that has the fix for Developer Edition and where Esri confirms that this will be fixed. Editing Time in DateTime Field in 2.0 DE? Hope that this helps! Chris ... View more

Raju, I apologize but I am not that familiar with Flex or Silverlight. From what I have seen, you will need to edit where the popups are configured in the code for the app. To add a hyperlink in HTML, add this line to the configuration. <a href="{YourField}" target="_blank"><B>More Info</B>  I hope that this will help!
