javascript - How do I correctly zoom to bounds in MapQuest? -

i'm attempting utilize mqa.tilemap.zoomtorect set view-port of given bounding box.

var cust; var rect = new mqa.rectll(); (var = 0, len = custs.length; < len; i++) { cust = custs[i]; poi = new mqa.poi({lat:cust.lat, lng:cust.lng}); map.addshape(poi); // works rect.extend(poi.latlng); // nil `rect'. } map.zoomtorect(rect, false); // fails

it appears rect values remain 0,0 both lr , ul properties. phone call results in next output in firebog

"networkerror: 500 internal server error - http://coverage.mqcdn.com/coverage?format=json&jsonp=mqa._covcallback&loc=nan,nan,nan,nan&zoom=2&projection=sm&cat=map%2chyb%2csat"

edit: i've added notes illustration adding shape works fine, poi object fine, inspecting poi.latlng fine.

if set poi's in collection can utilize collections getboundingrect method.

example:

var collection = new mqa.shapecollection(); collection.add( new mqa.poi( { lat: 0, lng: 0 } ) ); collection.add( new mqa.poi( { lat: 100, lng: 100 } ) ); map.zoomtorect( collection.getboundingrect() );
