I've been researching this topic and can't find much about it. I know you can add KMZs from ArcServer or ArcGIS online. That is not what I want to do.
Is there a custom widget that imports a KML/KMZ to the WAB 1.3 as a temporary layer for users? I know this is available with shapefiles, but it would be nice with KMZs.
