EditorWindow : ScriptableObject modifications not updated/applied

Hello,

I'm working a a custom EditorWindow which goals is to populate datas in a ScriptableObject.

 public class GameDBEditorWindow : EditorWindow{
 
    public GameDB gameDB;
    ...
    ...

}

 public class public GameDB : ScriptableObject{
    public string[] toolbarStrings = new string[] {"one","two","three"};
    ...
    ...
 }

I do not write the code that create the ScriptableObject instance neither the code that save it when it's modified - but those functions exist and work as expected.

If I do the following actions :

• Load the WindowEditor

• Save the assets using EditorUtility.SetDirty(this) and AssetDatabase.SaveAssets();

• The gameDB is correctly saved in the disk

• Add an entry in the toolbarString, let's say "four"

• Save again

• The toolbar displays in the editor is not updated

• Closing the editor and re-open change nothing

Any idea why ? Thanks
