ExpandableObject won't update text on property change in the UI

[@tmc_]

Hi, I have the following sample code which uses an expandable object converter to display and configure my object inside the indicator properties. It works all well, except for one small detail - when the property changes, it does not update the displayed text and only updates if I close and open the indicators window. Please refer to the animation below. How do I fix that so it updates just like plots for example? Thanks in advance!

using NinjaTrader.Gui;
using System;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;

namespace NinjaTrader.NinjaScript.Indicators.Samples
{
    public class SampleExpandableObjectIndicator : Indicator
    {
        [TypeConverter(typeof(ExpandableObjectConverter))]
        public class MyObject : NotifyPropertyChangedBase, ICloneable
        {
            public bool Boolean { get; set; }
            public int Number { get; set; }
            public string Text { get; set; }

            public MyObject() : this(true, 256, "Hello World!") { }

            public MyObject(bool boolean, int number, string text)
            {
                Boolean = boolean;
                Number = number;
                Text = text;
            }

            public object Clone()
            {
                return new MyObject(Boolean, Number, Text);
            }

            public override string ToString()
            {
                return string.Format("{0}, {1}, {2}", Boolean, Number, Text);
            }
        }

        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Name = "Expandable Object";
                Object = new MyObject();
            }
        }

        [Display(Name = "My object")]
        public MyObject Object { get; set; }
    }
}

MyObject (won't update the text)

Plot (updates the text when property changed)

I figured it out - had to add RefreshPropertiesAttribute to the properties. Below is the updated code as a reference for others that might encounter the same problem.

using NinjaTrader.Gui;
using System;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;

namespace NinjaTrader.NinjaScript.Indicators.Samples
{
    public class SampleExpandableObjectIndicator : Indicator
    {
        [TypeConverter(typeof(ExpandableObjectConverter))]
        public class MyObject : NotifyPropertyChangedBase, ICloneable
        {
            [RefreshProperties(RefreshProperties.Repaint)]
            public bool Boolean { get; set; }

            [RefreshProperties(RefreshProperties.Repaint)]
            public int Number { get; set; }

            [RefreshProperties(RefreshProperties.Repaint)]
            public string Text { get; set; }

            public MyObject() : this(true, 256, "Hello World!") { }

            public MyObject(bool boolean, int number, string text)
            {
                Boolean = boolean;
                Number = number;
                Text = text;
            }

            public object Clone()
            {
                return new MyObject(Boolean, Number, Text);
            }

            public override string ToString()
            {
                return string.Format("{0}, {1}, {2}", Boolean, Number, Text);
            }
        }

        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Name = "Expandable Object";
                Object = new MyObject();

                AddPlot(System.Windows.Media.Brushes.Red, "Result");
            }
        }

        [Display(Name = "My object")]
        public MyObject Object { get; set; }
    }
}
