Can't added ExtendedEvent to a Serialized Object

[malitvin]

When you add an Extended Event to a non MonoBehaviour class there will be a non reference exception on line 22 of ExtendedEventPropertyDrawer

The value field is null

yeah same here

if you need to fix this use those methods

    private void RestoreState( SerializedProperty property ) {
        if ( rList == null || eEvent == null ) {

            
            header = property.name;
            //var target = property.serializedObject.targetObject;
            //eEvent = fieldInfo.GetValue( target ) as ExtendedEvent;
            object o = GetTargetObjectOfProperty(property);
            eEvent = o as ExtendedEvent;
            foreach ( var item in eEvent.Listeners ) {
                item.Initialize();
            }

            rList = new ReorderableList( eEvent.Listeners, typeof( ExtendedEvent.GameObjectContainer ) );
            rList.draggable = false;
            rList.elementHeight *= 2;
            rList.drawHeaderCallback = DrawHeaderInternal;
            rList.drawElementCallback = DrawElementInternal;
            rList.onAddCallback = AddInternal;
            rList.onRemoveCallback = RemoveInternal;
        }
    }

    private static object GetValue_Imp(object source, string name, int index)

        //while (index-- >= 0)

        //return enm.Current;

        for (int i = 0; i <= index; i++)
        {

        }
