After a series of related bug fixes on the ListView element, this particular could not be reproduced anymore (2023.3.0b3).
Cancelling this 2023.2 tech release issue since the support for this release has come to end of life. Cancelling this 2023.2 port case does not affect any LTS or Unity 6 Beta/Preview that remain open.
2023.1 is no longer a supported version of Unity. Please see the corresponding 2023.2 port instead (if applicable).
After a series of related bug fixes on the ListView element, this particular could not be reproduced anymore (2022.3.16f1).
Reproduction steps:
1. Open the attached project
2. Open Inspector
3. Select Cube in Hierarchy
4. Under Testing script add multiple layers of data and try to remove the same data
Expected result: No errors are thrown
Actual result: Different errors are thrown almost for every action
Reproducible with: 2022.2.0a9
Not reproducible with: 2022.2.0a8
Notes: there are two different errors, one about layout when adding new elements and one is an exception being thrown due to elements being removed
Error on adding element higher in depth:
Layout update is struggling to process current layout (consider simplifying to avoid recursive layout): VisualElement unity-panel-container (x:0.00, y:0.00, width:454.00, height:939.00) world rect: (x:0.00, y:0.00, width:454.00, height:939.00)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)
Examples of exceptions on removing elements:
