Help needed on import function

[imsmart-tech]

I'm developing a service where people will write their own Javascript code. With it I want them to write modules. Users would also have to explicitely load a given module to use it.

Check the test code below. It does not work because _engine is null when I call ImportModule. I don't know if it's possible to pass back the engine object to the function or how to walk around this issue.

    public class SmartScript
    {
        private IJsEngine _engine;

        public void Test()
        {
            try
            {
                RunJS();
            }
            catch (Exception ex)
            {

            }
        }

        public void RunJS()
        {
            _engine = JsEngineSwitcher.Instance.CreateDefaultEngine();

            try
            {
                _engine.Execute("this.ImSmart = {};");
                _engine.EmbedHostObject("ImSmart", new SmartScript(true));

                _engine.Execute("ImSmart.ImportModule('Nest');");
            }
            finally
            {
                _engine.Dispose();
            }
        }

        public void ImportModule(string name)
        {
            string Code = "(function() { " +
                " this.ImSmart.Nest = function Nest(room){ " +
                " this.room = room; " +
                " this.temperature = null; " +
                " this.ShowRoom = DisplayNest; " +
                " this.SetTemperature = SetTemperature; " +
                " } " +
                " function DisplayNest() " +
                " { " +
                " return 'room is ' + this.room + '. Temperature is ' + this.temperature; " +
                " } " +
                " function SetTemperature(temp) " +
                " { " +
                " this.temperature = temp; " +
                " } " +
                " }());";

            this._engine.Execute(Code);
        }
    }
