I have set up the Identify widget and it works on layers within a web map, but when I add an "identify url", it brings back no results. In an earlier post you said that it had to be part of the base web map. Is that still the case? If so what is the purpose of having the "identify url"?
Mike,
The widget will work for any layers in the map if you have the widgets configuration NOT set to "Only These". But not adding your layer to the widget config means that all fields will be displayed and you can not use other features of the Identify widget with that layer like links and aliasing.
