Buffer Geometries (Geometry) returns null.Does anybody have a solution?

GaneshSreesakumar — Thu, 03 Nov 2011 05:26:52 GMT

I am using Ext 3.0 , google api and ArcGIS rest service.
i've included some part of the code below.
initialisation part :
            Geometry = new esri.arcgis.gmaps.Geometry("http:..................ArcGIS/rest/services/Geometry/GeometryServer");
                mapExtension = new esri.arcgis.gmaps.MapExtension(map);
These thing are included. Along with the following code

var params = {
   geometryType : "GLatLng",
   geometries : [longi,lati],
   inSR : 4326,
   outSR : 4326,
   bufferSR : 3857,
   distances : 1000,
   unionResults : true,
   unit : 9001,
   f : 'pjson'
   };
com.bs.bsMap.queryParam = params;
Geometry.buffer(params, self.resultOrganiser);

but in the callback function the result set is null when returned.

can anybody please help.........

Ganesh, Can you post the REST URL for this call? You can use the geometry service on sampleserver

Thank you Ravi , I am using the url which you have provided and still the problem exists..
Do you have any idea why this kind of error appears . I know definitely it is some sort of trouble with my code . The end result what i require is the boundary geometric points of a circle( in lat n lng) enclosing a center point (that i pass to the geometries). I think there is some problem with the parameters geometries and distances.

I cant figure out on what it is......

Ganesh,
Please share the REST URL. It will help determine if any of the parameters included in the request is incorrect. This URL can be captured when monitoring request/response from your application using fiddler or firebug.
