When performing a Day-2 Reconfigure action on a Cloud.NSX.Nat resource to remove all existing NAT rules, you encounter the following behavior:
The Submit button becomes greyed out.
The mouse cursor changes to a red warning/stop sign when hovering over the button, indicating it is disabled.
Despite the disabled visual state, clicking the button successfully submits the change and deletes all NAT rules.
Aria Automation 8.18.x
This is a user interface (UI) defect. While the UI visually disables the button when zero NAT rules are present, the underlying component fails to block user interaction, allowing the API call to be triggered upon a click.
This issue is officially resolved in a future release of VCF 9.
