Read-Only List unable to copy if property setter is private.

Environment:

Windows 10, 64-bit

OpenTAP 9.12.1

Editor 9.12.0

Issue

The Example below is a combination of 'List of Objects Example' and 'Read-Only List Example'. It demonstrates how a Read-only list can be embedded in a list of objects and also that it can be copied when a row in the list of objects is copied.

1. Demo 1 shows

• The list of objects can have any number of rows.
• The read-only list has a fixed number of rows which is the desired behaviour.
• The read-only list is copied when the row in the list of objects is copied.

4. Demo 2 show that all the properties of the read-only list are still editable.
5. Issue: It does not seem possible to create read-only properties and to also have the copy behaviour using the code below.

Question: Is it possible to have read-only properties in the read-only list and also have the read-only list be copied when it is embedded in a list of objects?

Demo 1:

ReadOnlyList2

Demo 2:

ReadOnlyList2-2

Code:

using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;

        [Display("Set 3")] Set3
    }

    public enum Option
    {
        [Display("Option 1")] Option1,
        [Display("Option 2")] Option2,
        [Display("Option 3")] Option3
