EditorJsonUtility in Unity 5.5

Hello,

according to the release notes of Unity 5.5

I wanted to try this as it sounds very useful for saving data from Editor scripts. However, for me, EditorJsonUtility doesn't generate a fileID for object references, not even an instanceID as before.

Here are my test scripts:

Code (CSharp):

1. using System;
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class Test : MonoBehaviour
7. {
8.     public GameObject reference;
9.     public Transform component;
10.     public string data;
11. }
12.  

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEditor;
5.  
6. [CustomEditor(typeof(Test))]
7. public class TestEditor : Editor
8. {
9.     public Test Target
10.     {
11.         get
12.         {
13.             return (Test)target;
14.         }
15.     }
16.  
17.     public override void OnInspectorGUI()
18.     {
19.         Debug.Log(EditorJsonUtility.ToJson(Target));
20.         Debug.Log(JsonUtility.ToJson(Target));
21.         base.OnInspectorGUI();
22.     }
23. }
24.  

I get this from EditorJsonUtility.ToJson:

Code (JavaScript):

1. {"MonoBehaviour":{"m_Enabled":true,"m_EditorHideFlags":0,"m_Name":"","m_EditorClassIdentifier":"","reference":{"instanceID":0},"component":{"instanceID":0},"data":"Test"}}

-> instanceID is 0 ??? no fileID!

JsonUtility.ToJson is atleast generating instanceIDs...

Code (JavaScript):

1. {"reference":{"instanceID":9326},"component":{"instanceID":9336},"data":"Test"}

Is this broken or has anyone worked out how to use this "feature"?

Did you ever figure this out? I have the same problem.

 

Also wondering what's up with this.
It doesn't appear to be a bug, but can someone explain this behaviour?

 

What file ID could it possibly give for a scene object? I've never used it, but I would assume it would work more effectively on an asset instead. Try it on a ScriptableObject saved to the disk, or a prefab, and see if you have better luck there.

 

Unity 2017.3.0p1
I've got an object with script that links two Transforms. When I serialize it by script below I see this: "instanceID": 0

        private static string GetParameters(GameObject go)

        {

            string ans = "";



            ans += EditorJsonUtility.ToJson(go,true);    // GameObject

            var components = go.GetComponents<Component>();



            for (int i = 0, len = components.Length; i < len; i++)

            {

                var componentString = EditorJsonUtility.ToJson(components[i], true);

                ans = ans.Insert(ans.Length - 1, "," + componentString.Substring(1, componentString.Length - 2));

            }

            return ans;

        }

 

I also have this problem with EditorJsonUtility.ToJson.
tried on an asset file and only the first level (0) is given, while content of .asset file shows the sub-level content.

 

Same probleme here, what is going on ?
