We are testing the polling place locator app. We are using our own geocoding, geometry and routing services. Everything is working fine except with the directions function, the blue line showing the route does not display (as it does with the ESRI world routing service). The textual information is shown correctly on the tab. I didn't modify anything in the code for that section other than replace the URL for the service. Do we need to modify something in our closest facility service? Or do I need to modify something in the application. Any suggestions are appreciated.
