how to build the polyline where Points crosses the international dateline

[NipaParikh]

Hi,

I've series of points that displays ship's locations as it moves.  I generate dynamic polyline from the series of the points.  But the problem I've having is there are ships that crosses the international dateline.  In that case I don't want to join points but instead generate two separate polylines on two sides.

Does anyone know how to do that?

I'm attaching the code on how I'm building the polyline dynamically.

In 2.3 release,
there is normalizeCentralMeridian method that you can use before adding graphic to graphicsLayer on the map.
http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/utils/GeometryUtil.html#normalizeCentralMe...

pseudo code:

var geometryService:GeometryService = new GeometryService("http://myserver/arcgis/rest/services/Geometry/GeometryServer");
        private function Normalize():void {
            var normalizeResponder:AsyncResponder = new AsyncResponder(normalizeResult_Handler, normalizeFault_Handler)
            GeometryUtil.normalizeCentralMeridian([myGraphic.geometry],geometryService,normalizeResponder);
            }
        
        private function normalizeResult_Handler(geometries:Array,token:Object = null):void {
            for each (var geometry:Geometry in geometries){
                myGraphicsLayer.add(new Graphic(geometry));
            }
        }
        private function normalizeFault_Handler(geometries:Array,token:Object = null):void {
            
        }
