Why does my Unity Serialization not work? Do i miss something?

Questions & Answers

Like my Question, what am i doing wrong? I feel like i read every post so far but really nothing helped…

using UnityEngine;
using UnityEditor;
using System;
using System.Collections;
using System.Collections.Generic;

[Serializable]
public class QuestEditor : EditorWindow 
{
    //[SerializeField]
    //public List<QuestEditorNode> Nodes;

    [SerializeField]
    private int x;

    void OnEnable()
    {
        Debug.Log("OnEnable " + x);
        x = 42;
    }

    void OnDisable()
    {
        Debug.Log("OnDisable");
        x = 66;

    }

    #region Unity Menu Tab
    [MenuItem("Quest Editor/Show Window")]
    public static void ShowWindow()
    {
        EditorWindow.GetWindow<QuestEditor>();
    }
    #endregion
}

i compressed it hard now. like you see in the first Line my attempt is to save a list of Nodes. But since this x saving doesn’t even work, i don’t care about my Nodes for now…

My Code should do nothing more to just save this x when my EditorWindow is closed. I read that this should be done by just adding [Serializable] and [SerializeField] to the class/variables…

I thought EditorWindow instances are destroyed when they are closed. There is nothing to serialise as it doesn’t exist in the scene or the project.
Maybe look into custom editors of a GameObject?
