Reshaping using geometryservice throws error Error: E0002E: Use a subclass instance

Question

I have a geometryservice that reshapes a feature.

I select a feature then call the geometryservice.

myGeometryService.reshape(selectedGraphic.geometry,drawnLine)

The first time I call the service it works fine.

If I then select the same feature again then try and reshape it the event returns no geometry and gives 'exception thrown by getter' .. Error: E0002E: Use a subclass instance.

I am not using the edit widget and it is the version 2.5 of the flex API.

Hey Rod,

I tried GeometryService.reshape() at my end with 2.5 api, it seems to working fine for me. Could you send me the complete test case/application or the full stack trace you have? Will be easier to debug

Meanwhile, here's what i am doing in my resultHandler:
var reshapedPolygon:Polygon = event.result as Polygon;
var newGraphic:Graphic = new Graphic(myPolygon);

I have changed it from a graphic.geometry to a polygon and it is still doing the same thing. It works the first time I reshape then when I select the feature, assign that to my selected graphic object and then try and reshape I get this error. Here is a code snippit. It returns the error on the reshapecompletehandler. private function reshapepolygon():void { map.removeEventListener(MapMouseEvent.MAP_CLICK, map_mapClickHandler); reshapedrawTool.activate(DrawTool.POLYLINE); } protected function reshape_drawEndHandler(event:DrawEvent):void { var drawnLine:Polyline = Polyline(event.graphic.geometry); myGeometryService.addEventListener(GeometryServiceEvent.RESHAPE_COMPLETE, reshapeCompleteHandler); var myPolygon:Polygon = Polygon(selectedGraphic.geometry); myGeometryService.reshape(myPolygon,drawnLine) reshapedrawTool.deactivate(); map.addEventListener(MapMouseEvent.MAP_CLICK, map_mapClickHandler); } private function reshapeCompleteHandler(event:GeometryServiceEvent):void { Alert.show("reshape Complete") var newAtttrs:* = ObjectUtil.copy(selectedGraphic.attributes); var myPolygon:Polygon = new Polygon; myPolygon.rings = event.result.rings; var newGraphic:Graphic = new Graphic(myPolygon, null, newAtttrs); incidentsPolygonLayer.addEventListener(FeatureLayerEvent.EDITS_COMPLETE,editscomplete) incidentsPolygonLayer.applyEdits([ newGraphic ], null,incidentsPolygonLayer.selectedFeatures); } The geometryservice.reshapeLastResult is the same as the event returns. com.esri.ags.geometry.Geometry (@afd16b9) defaultSymbol extent spatialReference null type The mypolygon and drawnline both seem to look OK.

That error means you're using an instance of the Geometry base class rather than a Polygon etc.
