DirectionsLeg.start_address - Editable in results?

[Charles McCulloch]

I am trying to prepend some text into the start_address property which is returned in the DirectionsLeg object..  I want to associate business names with these waypoints in the returned directions.

For some reason, and I'm not ruling out developer error here, only the first leg is being updated. . I've dumbed down the code as much as I can to test this out.  My code is as follows:

            response.routes[0].legs[0].start_address = 'Store # 0: ' + response.routes[0].legs[0].start_address;

            response.routes[0].legs[1].start_address = 'Store # 1: ' + response.routes[0].legs[1].start_address;

            response.routes[0].legs[2].start_address = 'Store # 2: ' + response.routes[0].legs[2].start_address;

            response.routes[0].legs[3].start_address = 'Store # 3: ' + response.routes[0].legs[3].start_address;

            response.routes[0].legs[4].start_address = 'Store # 4: ' + response.routes[0].legs[4].start_address;

            response.routes[0].legs[5].start_address = 'Store # 5: ' + response.routes[0].legs[5].start_address;

            response.routes[0].legs[6].start_address = 'Store # 6: ' + response.routes[0].legs[6].start_address;

            response.routes[0].legs[7].start_address = 'Store # 7: ' + response.routes[0].legs[7].start_address;

            directionsDisplay.setDirections(response);

My directions, however, come out this way... See attachment.  Only the first (element 0) address is shown with the updated text.  The remaining legs remain unchanged.

I am not returning multiple routes (provideRouteAlternatives is false), so there is only one route with multiple legs from start, to each waypoint, to the end point.  I am not sure what I'm missing, please advise?

Thanks,
