Bug Error displaying nested arrays in the inspector

After the transition to 2020.3.6, there was a problem with displaying nested arrays if there are more than two of them in the class. The picture shows an example. If you remove one array, or remove the nesting, the display is correct.

Code (CSharp):

1. public class NewBehaviourScript : MonoBehaviour
2. {
3.     [Serializable]
4.     public class Test
5.     {
6.  
7.         public List<GameObject> nestedTestArray01;
8.         public List<Transform> nestedTestArray02;
9.     }
10.    
11.     public List<Test> TestArray;
12. }

 

I've tried 2020.2.6, 2020.3.7 & 2021.1.6 and got the same issue. I only wanted to upgrade to reorder arrays! I can now do that but cant get them to expand to edit.

The only thing I've found to do so far is put in [NonReorderable] when you want to edit and remove [NonReorderable] when you want to move nested fields up and down.

 

Just want to bump this and check to see if anyone here has submitted a proper bug report from within the editor so I don't bother duplicating it. Can also confirm that the [NonReorderable] hack works.

 

The error disappeared after updating to 2020.3.8

 

I'm still experiencing this issue with 2020.3.12. I was able to clear it up for a little while by deleting the entire Library folder and forcing it to rebuild but it did eventually reappear.
Typically after restarting Unity it will work for a very short period of time before starting again.

 

Did you find any solution to this? I am still experiencing a similar issue in Unity 2020.3.21f1, but now it is when expanding serialized classes insode a nested list

 

Im getting this too, in 2021.2.7f1 which is the latest version at the time of writing.
It's drawing lists incorrectly, here's an example of a List of a custom ScriptableObject subtype, Color, and string:



Interestingly, when you click on one of the elements in the list, it shows up while you hold down LMB. When you let go, it disappears again. It doesn't let you edit the element at all.

The only fix Ive found is downgrading to Unity 2020, which Id prefer not to have to do. Anybody found any solution to this?

 

I am seeing this EXACT same issue, including the LMB weirdness where they temporarily show up.
I can't add stuff to my array now and I don't want to change Unity versions if possible. Anyone found a solution or workaround? Happy new year.

 

Confirming the same issue with display of scriptable object array in version 2021.2.7f1.

What is interesing the issue appears only on my second monitor and only if it is not set as a main monitor.

 

Having the same problem in 2021.3.3f1.
That said, its always only Element 0 that is messed up
Also the clicking with LMB on element 1 stuff while element 0 is supposedly open also bugs it. But if element 0 is closed it works.
The absolute jank solution i have right now is i create one extra element and set them up and by the end of it i move the 0' element down and delete it.

 

+1 Same issue here - 2021.3.3f1.
-Nice workaround!

 

2021.3.4f has the same problem STILL

 

I am facing the same issue in "2021.3.3f1" . Same issue for all Beta Versions as well.
The workaround, as already said, is create an additional element, move the 0 element at the end and edit it (And move again at 0 index). Very annoying.

Thanks

 

i fixed this issue with a hint from Voltonik_ in another post

-> As a temporary fix till its fixed I used the [NonReorderable] Attribute to disable the reorderable list rendering

this did it for me!!

Hi,

I'm having same problem using Linux 20.04 LTS, since I updated to Unity 2021.3.3f1 LTS, and after update to 2021.3.4f1, the problem continues, could you fix it? plz

 

Both great workarounds, thanks for the brainstorm here!

 

Currently affected versions are 2020.3.35, 2021.3.3 and 2021.3.4. Use an earlier version of the engine to fix the issue.

 

Great to see new bugs coming in recent LTS. How is it possible? It should be a very stable version of the engine.

 

I confirm the existence of the problem in 2021.3.3, 2021.3.4, 2020.3.35.

The first element of an array/list (not nested) is displayed incorrectly (on top of the list)

 

Just checked and indeed, the problem can be found on latest LTS which is 2020.3.35, we downgraded to 2020.3.34 and the problem is not there.

 

please fix it!

 

jc, release at least a hotfix for these so we dont have to wait three weeks for .5f1! The latest LTS releases were horrible bad and rushed, what's happening unity

 

Thank you ElPeanuto for the workaround.

 

Was just about to post about this issue...
I am also having this bug.

Unity version: 2021.3.4f1 LTS

Issue: Any array in the inspector will not show the 0th index properly.

Picture:

 

I hope they will fix it iin 2021.3.5 working with Apple silicon is already hard and crashes alot

 

Having the same issue in 2021.3.4f1. Did upgrade today to LTS and wasn't expecting these issues.

 

Ok, so I got a brainfart today and thought waht if it isn't reordable and it actually solved the issue.
Just add
[NonReorderable]
on top of your list/array and it will render properly in the inspector, ofc you won't be able to reorder the arrays but at least they'll render correctly

 

The Unity team has already detected this error and it is expected that the patch to correct it will be released in version 2022.2.0a13.

 

Same error in 2021.3.4f1, which beginner write those dumb code? again and again seriously?

 

same in unity 2021.3.4f1

 

Same also in Unity 2021.3.4. Looks like it will be fixed soon

Yay! Looks like it has been fixed on the next LTS patch:

Code (CSharp):

1. Fixed in: 2021.3.5f1

 

VERSION 2022 - still with the problem

 

Happening in 2020.3.36f1

 

I switched to 2022 and it was solved!

 

Super annoying bug. We can't switch to 2021. We are on 2020.3.36f1 and hoped it was fixed with 2020.3.37f1...but,

The issue appears to be (UUM-7683)and it is listed as a known issue for 2020.3.37 in the release notes.

Inspector Framework: List element overlaps everything when using Serializable struct/class (UUM-7683)

 

i use 2022 - it is solved, why cant you switch?

 

An infinite number of reasons - this is not the solution - unity needs to backport to older versions.

 

Despite the list of known issues saying otherwise, the issue has been fixed in version 2020.3.37f1:

 

I was released my game with this version and i get soo many crashes and anr, i roll back to unity 2020.3.25 and everything works fine

 

Unity says that it was fixed in 2020.3.37f1 here: https://issuetracker.unity3d.com/is...ng-when-using-serializable-struct-slash-class

However, I'm on 2020.3.39f1 and I still get this issue when using nested properties that have foldouts...

 

I had this error and found a workaround posted elsewhere on this forum. The issue is with Reorderable arrays/lists. The handle on the left allows you to reposition them. If you don't care for reorderable lists, use the inspector attribute [NonReorderable] in front of your field definition. The lists return to their old format and don't overlap. This'll work in all older versions with bugged reorderable lists

 

Thank you for this tip. I've suffered these problems on a few of my personal projects for a long time now.

Finally did something about it because the Visual Scripting editor straight up crashes the whole editor with this bug. Seems like a pretty significant issue that needs to be fixed, but your solution helped in the meantime

 

Using [NonReorderable] attribute is not a workaround, it's a different solution that may or may not be acceptable for your specific use case. In my case, I want users to be able to reorder lists of my custom property so this is not a solution.
I tried searching for this in Unity's issue tracker but all the issues I've found say that it's been fixed in my Unity version but it's clearly not the case for me...
