hi Im trying to adjust the example ShowVertex feature action to suite my porposes  by adding another feature action to the demo widget and send the name and ID of a feature to the widget.

I have , heres my feature action code

define([
   'dojo/_base/declare',
   'jimu/BaseFeatureAction',
   'jimu/WidgetManager'],
   function(declare, BaseFeatureAction, WidgetManager){
      var clazz = declare(BaseFeatureAction, {

      iconFormat: 'png',

      isFeatureSupported: function(featureSet){
         return featureSet.features.length > 0 && featureSet.features[0].geometry.type !== 'point';
      },

      onExecute: function(featureSet){
         WidgetManager.getInstance().triggerWidgetOpen(this.widgetId)
         .then(function(myWidget) {
            var id
            var name
         featureSet.features.forEach(function(f){
            id = f.id
            name = f.name
         });
      myWidget.AddtoSelected(name,id);
