I have these codes. I'm wondering how do I use Lang.Hitch for this because of this error TypeError: Cannot read property 'selectFeatures' of undefined.
function CreateGraphics (evt) {
CODES HERE.......................
var graphics5= new Graphic(geoBuffer, symbolBuffer, attr5, infoTemplate5);
//map.graphics.add(graphics5);
ShowSelectedFeatures (graphics5);
}
/////////////////////////////////////////////////////////////////////////////////////
function ShowSelectedFeatures(graphicsLine) {
var featureCollection = {
"layerDefinition": null,
"featureSet": {
"features":graphicsLine,

};
featureCollection.layerDefinition = {
"geometryType": "esriGeometryLine",
"objectIdField": "ObjectID",
"fields": [{
"name": "ObjectID",
"alias": "ObjectID",
"type": "esriFieldTypeOID"

};
// Create a new feature layer
var FLayer = new FeatureLayer(featureCollection, {
mode: FeatureLayer.MODE_SELECTION,
outFields: ["*"],
infoTemplate: infoTemp
});
FLayer.setSelectionSymbol(lineSymb);
map.addLayer(FLayer);
}
