If bad route is requested in "Get directions example", map is never refreshed again even w/good route

Summary: if a "bad" (unobtainable) route is requested once using 
displayDirections, the map will never show a route again (like when a "good" 
to/from re-entered) on the map, but directions will be updated indicating a 
successful route was found.

1. 
http://jquery-ui-map.googlecode.com/svn/trunk/demos/jquery-mobile-example.html#j
query-mobile-example-3.html
2. Use default to/from and hit "Get directions" - map and directions - OK
3. Enter a bad "To" value (Hilo, HI, USA), leave Got. in "From" field
4. Hit "Get directions" - route is cleared from map, no directions - OK
5. Enter Stockholm, Sweden again in "To" field, hit "Get directions" ---> 
directions are updated, but map is not: no route shown even though success case.

What is the expected output? What do you see instead?
The route to be shown on map whenever route is possible.

Please use labels and text to provide additional information.
One fix is to add the line indicated with -->  <-- to jquery.ui.map.js:187

} else { 
instance.services.DirectionsRenderer.setMap(null);              
--> instance.services.DirectionsRenderer = null; <--
}
