Hey everybody, In my drawing app, I want  to add the possibility of buffering a point. I got it to work, but I have one issue. When I run it the first time everything goes ok. User checks the buffer checkbox, types in a buffer distance, selects the point button, clicks on the map and the buffer gets added to the map. When I run it a 2nd time, it looks like it works again like it is supposed to, but this time two identical buffer get added. When I do it a third time 3 identical buffers get added and so on. It seems that geometryService.on("buffer-complete") runs as often as I used the buffer before. Here is the code snipped that is responsible for adding the buffer:   function addToMap(evt) {        Uni();        if ( evt === undefined){             console.log("undefined");        } else {             toolbar.deactivate();             var Testcolor = cp.value;        if (Testcolor == ""){             newColor = newColor;        } else {             docolor();        }        switch (evt.geometry.type) {             case "point":             case "multipoint":             symbol = new SimpleMarkerSymbol(SimpleMarkerSymbol.STYLE_CIRCLE, myNumber,             new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID,             new Color(newColor), 1),             new Color(newColor));             break;             case "polyline":             symbol = new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new Color(newColor), myNumber)             break;             default:             symbol = new SimpleFillSymbol(symbolfill, new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID,             new Color(newColor), myNumber), new Color(newColor));             break;        }        graphic = new Graphic(evt.geometry, symbol);        if (dijit.byId("BufferCheckBox").checked && evt.geometry.type == "point" ){             params = new BufferParameters();             params.geometries  = [ evt.geometry ];             params.distances = [ dom.byId('BufferText').value ];             params.geodesic = true;             params.bufferSpatialReference = new SpatialReference({wkid: 102100});             params.outSpatialReference = map.spatialReference;             params.unit = Unit_Line;             geometryService.buffer(params);             geometryService.on("buffer-complete", function(evt) {                  var Buffsymbol = new SimpleFillSymbol("none", new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new Color(newColor), 2), new Color(newColor));                  Buffgraphic = new Graphic(evt.geometries[0], Buffsymbol);                  map.graphics.add(Buffgraphic);                  var operation2 = new CustomOperation.Add({                       graphicsLayer: map.graphics,                       addedGraphic: Buffgraphic             });             undoManager.add(operation2);        });       } Any help is appreciated!
