We have ags portal 10.4 with maps-services referenced from a clustered ags 10.3.1 stack.
I have created a webmap on our portal site, that references layers from our ags cluster (these layers have been registered on portal as items)
The above layers are all mapservices.
I am using webAppBuilder2.0 developer edition.
When I add the webmap as the map for my application, I leave all layer options checked on the layer list
widget options. I also have left the options for the attribute table as they are out of the box.
When I launch the the application from web app builder, open the layer list, and open attribute tables
