Error rendering drawer for AssetReference property

unity editor ver : 2018.2.6f1
addressables ver: 0.3.3 - preview

AssetReferences in my code are not rendered on Inspector

Code (CSharp):

1.  
2. public class TestBehaviour : MonoBehaviour {
3.     [System.Serializable]
4.     public class DataSet {
5.         public int intData;
6.         public string stringData;
7.         public AssetReference assetRefData;
8.     }
9.     [SerializeField] public DataSet dataset;
10. }
11.  

error message:

Error rendering drawer for AssetReference property Dataset.asset Ref Data.

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

It is rendered properly when AssetRenference is member of MonoBehaviour(ScriptableObject)

 

Thanks for reporting this bug. I've created a bug for it internally.

The same error also occurs in version 0.3.5 Is this bug always fixed?

 

This bug was not fixed in 0.3.5. It is still on the list to attack.

 

Any eta on this? Had to revert back to 0.2.2 to be able to use the system.

 

I did not get an error, but it will be drawn with None if the address is one of the "implied" address. (The greyed out sub-address resulting from dragging a folder into Addressables pane, and everything including Scenes/Resources in the group "Built In Data")

Using Debug mode of the inspector will reveal the real value inside.

 

Ok I did get an error now. It happened when `AssetReference` member is not at the root of selected inspector drawing target. Submitted as a bug case #1082379

If anyone want a dirty fix so that at least the editor is not crashing altogether, go to the package's source code and change the error line to this :

Code (CSharp):

1.             if (assetRefObject == null)
2.             {
3.                 var p = property.FindPropertyRelative("m_assetGUID");
4.                 EditorGUI.PropertyField(position, p , new GUIContent());
5.                 //Debug.LogError("Error rendering drawer for AssetReference property " + label.text + ".");
6.                 return;
7.             }

When the bug occurs it will draw only the GUID box. You could manually copy asset's GUID to this box for the time being. (Not sure of side effects?)

 

Unity : 2018.2.12f1, 2018.2.1f1
Addressables: 0.4.6 - preview

Issue still present, but now it doesn't print a warning since those lines were removed. Any news on this? I saw that the bug that @5argon posted above link is marked as fixed, but I still have the issue.

 

How it works right now is that the field completely disappears if the drawer found a problem digging out the inner variable to draw. (Same situation, but nested fields will be blank instead of a log message) See this, below Element 0 is supposed to contain the AddressableAsset field. Only outmost AddressableAsset fields are drawn.



If you want a quick fix to at least see something in this case, you can edit the code to my drawer according to here https://forum.unity.com/threads/assetreferencedrawer-does-not-dirty-the-serialziedproperty.568894/
