onChangeAsyncDebounceMs not properly debouncing about form HOT 1 CLOSED

The disabled state you're looking for can be done with a single extra boolean:

<form.Subscribe
  selector={(state) => [state.canSubmit, state.isValidating, state.isSubmitting]}
  children={([canSubmit, isValidating, isSubmitting]) => (
    <button type="submit" disabled={!canSubmit && !isValidating}>
      {isSubmitting ? '...' : 'Submit'}
    </button>
  )}
/>

However, I'm not sure that there's a bug here. When you're typing, the following happens:

• It waits 1s to cooldown the typing to trigger a onChangeAsync function call
• After this 1s, if there is any other user input, it will:
  • Trigger a new onChangeAsync function call
  • Trigger a signal to the old onChangeAsync so you can cancel behavior if you'd like

And, according to my testing here - is exactly how this works currently, even in your unmodified code sample

from form.
