Hello! I am creating an Operations Dashboard that shows incident data and road closure data. There are 4 layers in total and they are all hosted on ArcGIS Online. Layer Names: 1. QA Road Blocks (Point) 2. QA Road Closures (Line) 3. QA Road Detours (Line) 4. Incidents The 3 QA Road layers are all sublayers of a "QA Road Closures" layer. My issue is when I activate the popup for the QA Road Closures Layer (#2 on the list) OD shows a popup that is formatted for the QA Road Blocks layer (#1 on the list). The image below shows the popup working correctly for the QA Road Block Layer. The image below shows the popup incorrectly displaying for the QA Road Closures Layer. This is what the QA Road Closures popup should look like. Has anyone else come across this issue? Any help would be much appreciated! Thank you! Chris ... View more

Just curious if Esri removed it, or I messed up something. Thanks! ... View more

Hello all! I have a app that I created using Web AppBuilder (WAB) Developer Edition. We are hosting the app on our web server. The map and all the layers are hosted on ArcGIS Online (AGOL). I have configured the Esri Proxy service that is available on GitHub in order load the app without prompting for AGOL credentials. The app that I created has the "out of the box" print widget enabled. When the proxy is disabled, and the user must login manually when the app loads, the print widget works fine. When the proxy is enabled for the app, the print widget does not work. ==================================================================================== Here is the error I get on Fiddler web debugger: {"error":{"code":400,"message":"Unable to complete operation.","details":["Error executing tool. Export Web Map Task Job ID: ID12345ABCDE : Layer \"Road Detours\": Failed to create layer from service at https://our_agol_server/XtlHFoXqFDQ/arcgis/rest/services/Training_Road_Closures/FeatureServer/2.\nLayer \"Road Closures\": Failed to create layer from service at https://our_agol_server/XtlHFoXqFDQ/arcgis/rest/services/Training_Road_Closures/FeatureServer/1.\nLayer \"Road Blocks\": Failed to create layer from service at https://our_agol_server/XtlHFoXqFDQ/arcgis/rest/services/Training_Road_Closures/FeatureServer/0.\nFailed to execute (Export Web Map).\nFailed to execute (Export Web Map Task)."]}} ===================================================================================== These three layers (Road Closures, Detours, and Blocks) are the only layers on the map that need to utilize the proxy. It would seem that the "out of the box" proxy widget is not "proxy aware". Is there anyone who has had a similar situation and found a solution or work around? Thanks in advance! Chris ... View more

Hello all! I am working on a road closure app that will be constructed using the Web AppBuilder (Developer Edition). Because it will be embedded into another website we are going to host it locally and utilize the Esri proxy (from GitHub) to bypass the need for credentials. I am having issues when trying to access hosted layers from ArcGIS Online. I needed to add the "Access-Control-Allow-Origin" to the page header to access our organization's ArcGIS Online Account for the app to work. When I add this, the browser then comes back with the following error: "The 'Access-Control-Allow-Origin' header contains multiple values '*, *', but only one is allowed. Origin 'www.mysite.com' is therefore not allowed access." I have checked both the app's page and the proxy's page on IIS and I cannot locate a second value. Where do I need to go to find this second value? Thank you! P.S. I am new to CORS, so I am learning as I go. ... View more
