Google Street View widget error in SFV 2.0

SreeS — Tue, 17 Aug 2010 18:26:10 GMT

I was using Google Street View in SFV 1.3 I made some changes to it to use it in SFV 2.0.

But im getting the error shown in the jpg after I activate the GSV and click on map.

When I traced, I found that the problem is with geometry projection:

geometryService.project([ mapPoint as Geometry ], outSR) ;

Sree,

Just change the mentioned line to this

geometryService.project([mapPoint], outSR);

"Hidden" far down on the "Migration from 1.3 to 2.0" page, http://help.arcgis.com/en/webapi/flex/help/index.html#migrating.htm.

* Inputs for GeometryService are now geometries instead of graphics.
    //1.3:
    geometryService.project(graphics, new SpatialReference(32618));
    //2.0:
    geometryService.project([graphic.geometry], new SpatialReference(32618));

Which I think is the same as Robert's suggestion...

Sree,

I am not sure what is going wrong either here is all I have in my mouse down event handler

var mapPoint:MapPoint = map.toMapFromStage(event.stageX, event.stageY);
     var outSR:SpatialReference = new SpatialReference(4326);
     geometryService.project([mapPoint], outSR);

Hi,
I am also getting a load error with the SV widget in V2.0.
The attached image sows the Load Error. Once this error is closed the widget works correctly.
Any ideas why this "Application Error" occurs?
I am guessing this is something small - it is the first widget I have integrated into the Flex Viewer 2.0 so not sure if it is a problem with an additional file.
I have updated the GeometryService from the above file (StreetView.mxml.txt) to point to my local geometry service and this is working fine.
I am using Flex SDK 4.1
Thanks,
Brendan

guys,

Does your projection complete look something like this/

var geom:Geometry = (event.result as Array)[0];
    var mapPoint:MapPoint = geom as MapPoint;
    var lng:String = mapPoint.x.toFixed(12);
    var lat:String = mapPoint.y.toFixed(12);
    // launch street view
                               etc etc

Hi,
My code as follows:

   private function projectCompleteHandler(event:GeometryServiceEvent):void
   {
    
    var mapPoint:MapPoint = (event.result as Array)[0]as MapPoint;
    var lng:String = mapPoint.x.toFixed(3);
    var lat:String = mapPoint.y.toFixed(3);
    // launch street view
    var url:String  = "http://gis.kilkennycoco.ie/flex/streetview/index.html?lat=" + lat + "&lng=" + lng;
    var window:String = "_blank";
    var features:String = "toolbar=no,location=no,resizable=no,directories=no,status=no,scrollbars=no,copyhistory=no,width=600,height=400";
    
    var WINDOW_OPEN_FUNCTION : String = "window.open";
    ExternalInterface.call( WINDOW_OPEN_FUNCTION, url, window, features );
    
    CursorManager.removeAllCursors();
   }

Thanks for getting back to me,
Brendan

Now you will not be able to use my whole code word for word as I do things with the Flexviewer2.0 that you will not have but here is my code and it works fine. Maybe you can see where you are going wrong.

Finally got the Streetview widget upgraded and working from SFV 1.3 to 2.0 and then I came across this post 🙂

One request to make the widget work better for my purposes - how could you remove the streetview cursor from the mouse once the widget is closed? When the widget is closed there should be no reference at all to anything in the streetview.mxml.

Thanks for the help!

Phillip,

my code already does that is indicated in the code below:

private function widgetClosedHandler(event:Event):void
   {
    map.removeEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
    map.panEnabled = true;
    map.cursorManager.removeCursor(map.cursorManager.currentCursorID);
    setMapNavigation(null, null);
   }

Robert,

Thanks! When I implemented your code the cursor symbol just would not disappear after closing the widget. I had to reiterate that line of code you had indicated to make it work for me - probably not the most elegant method but it seems to work so far:

private function widgetClosedHandler(event:Event):void
   {
    map.removeEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
    map.panEnabled = true;
    map.cursorManager.removeCursor(map.cursorManager.currentCursorID);   
    setMapNavigation(null, null);
    map.cursorManager.removeCursor(map.cursorManager.currentCursorID);   
   }

Thank you Robert and Philipp,
My errors have disappeared too, and the Street View widget is now working perfectly.
Thanks for your help (as ever).

How would one remove the google cursor when the widget is minimized?? Right now it does this when the widget is closed but it makes sense to me to duplicate that function for when the widget is minimized..

Thank you!!

Phillip,

You would just add a minimized event handler to the widget template and have the remove cursor code there.
