Hello,
I am working with Web Appbuilder Developers Edition 2.0 and am trying to pass query parameter through a URL to select and zoom to a map feature. I was able to get that to work with a map service containing only one layer by following the ESRI example query=<layer name>,<field name>,<field value>.
I also have a map service with several grouped layers and I want to query one of those. The same ESRI help guide states: For a sublayer in a group of map services, use <layer id_sublayer id> as the layer id. This is confusing to me and have tried many different variations but cannot get it to work.
