UI Builder button EventListeners stop working when the UI Document gets disabled and re-enabled in Play Mode

--

-

How to reproduce:
1. Open the “UIBuild.zip“ project
2. Open the “SampleScene”
3. Enter the Play Mode
4. Click on the Button in the Game View (to see that the button click event is registered)
6. In the Hierarchy select the "GameObject"
7. Disable and re-enable the UI Document Component
8. Click the Button again
9. Observe the Console window

Expected results: The Button click event is being listened to and displays “I am working“ in the Console after clicking it
Actual results: The Button click event is not being listened to and does not display “I am working“ in the Console after clicking it

Reproducible with: 2021.3.34f1, 2022.3.18f1, 2023.2.7f1, 2023.3.0b4

Reproduced on: Windows 11 Pro
Not reproduced on: No other environment tested

Note: The reporter states that “This seems to only happen with button ClickEvent listeners because other listeners seem to work after reenabling”

  1. Resolution Note:

    Everything here is working as intended. Elements are regenerated when UIDocument gets disabled and re-enabled. Callbacks registered during the Start method refer to elements that no longer exist, hence why they aren't invoked anymore.
