CoordinateMenu Widget

Trying to recompile this widget for FV 3.0, not getting any errors but the widget hangs when you try to project a point.

Here;s my attempt to change the code in the Projector.as ...can anyone see why this wouldn't work?

public function projectPoint(mapPoint:MapPoint, toWKID:Number, callbackFunction:Function, errorFunction:Function = null):void   {    this.geometryService = new GeometryService(this.geometryServiceURL);    this.geometryService.addEventListener(GeometryServiceEvent.PROJECT_COMPLETE, callbackFunction);    if (errorFunction != null)    {     this.geometryService.addEventListener(FaultEvent.FAULT, errorFunction);    }    else    {     this.geometryService.addEventListener(FaultEvent.FAULT, function():void     {      Alert.show("Error projecting coordinates.","Error");     });    }    var projParams:ProjectParameters = new ProjectParameters();    projParams.geometries = [MapPoint as Geometry];    projParams.outSpatialReference = new SpatialReference(toWKID);    // Note: GeometryService takes in geometries instead of graphics as input    geometryService.project(projParams);

Not a programmer but wouldn't you need to convert mapPoint and not MapPoit to a geometry.

var projParams:ProjectParameters = new ProjectParameters;
   projParams.geometries = [mapPoint as Geometry];
   projParams.outSpatialReference = new SpatialReference(toWKID);
   // Note: GeometryService takes in geometries instead of graphics as input
   geometryService.project(projParams);

This seems to be working for me.

Was wondering if you got this working, and if so, if you would be kind enough to share the "modified" source?

Thanks,

The only file that needed to be changed for the widget was the Projector.as

Thank you. I tried to make the changes to projector.as and got it to compile without errors or warnings, but was getting no response in the map.

Must have made a type somewhere, as it is working fine now using your projector file.

At least, the GUI is. Do you have the context menu option functioning as well?

Thank you,

It appears to be working. I don't use this portion of the widget but I turned it on real quick to check. Remember to at the widget in the UI elements.

Here is the source code for everything. Let me know how it goes.

Got it. Thank you.

Turns out that I "disabled" it by following this thread: http://forums.arcgis.com/threads/18142-remove-items-from-map-context-menu

Removed more than expected from the contect menu.
