I just upgraded to WAB Developer Edition version 2.7. When I use the Search tool or pass a query through URL parameters, the search result highlights with a nearly opaque orange polygon. In the previous version, you could click elsewhere on the map to deselect the polygon and the orange would go away. Now, the polygon persists like a drawing object and I have no way to remove it.
Test URL: URL Parameter Search
Or you can go to http://gis.douglascountyks.org/propertyviewer/ and search for 107-26-0-00-00-005.00-0 (this is a PIN number, just FYI). Click away from the highlighted property, and the orange polygon persists.
I can restore a backup version of my website, but I need to figure out how to fix this so that I can continue to use the latest version of Developer Edition.
