        private IRecordContext _recordContext;
        private bool _inDesignMode;
        private IGlobalContext _globalContext;

       public IncidentOpenComponent(bool inDesignMode, IRecordContext context, IGlobalContext gContext)
        {
            this._inDesignMode = inDesignMode;
            this._recordContext = context;
            this._globalContext = gContext;

        if (!_inDesignMode && _recordContext != null)
            {
