Bug action.ChangeBinding(0).Erase() issue

Hello,

I'm implementing a system where all the actions and bindings are created at runtime. Now, is there a proper way to remove an action binding, because Erase seems to misbehave when an action has a single binding:

Code (CSharp):

1. InputAction action = new InputAction("MyAction", InputActionType.Value);
2.  
3. action.AddBinding(new InputBinding("Keyboard/a"));
4.  
5. Debug.Log($"Bindings count: {action.bindings.Count}"); // Prints 1
6.  
7. action.ChangeBinding(0).Erase();
8.  
9. Debug.Log($"Bindings count: {action.bindings.Count}"); // Also prints 1

This seems like a bug, but am I missing something here? Is there another way to remove bindings? Do I have to refresh the action somehow after erasing a binding?
Thanks in advance!

 

Looks like a bug. Thought that one was fixed a while ago. Which version are you on?

 

I'm using Unity 2021.3.15f1 and Input System 1.4.4.
