SimpleForm isDirty is always true if ArrayInput is used about react-admin

Reproduced, thanks!
Appreciate the great sandbox btw 😊

Until this is fixed, you can use the same workaround we used in SaveButton.tsx:

    const { dirtyFields, isValidating, isSubmitting } = useFormState();
    // useFormState().isDirty might differ from useFormState().dirtyFields (https://github.com/react-hook-form/react-hook-form/issues/4740)
    const isDirty = Object.keys(dirtyFields).length > 0;

Yes. We use the same workaround. 🙏

Just one hint, this only works partially. If I change one value in the array input and then revert the changes the field is still listed in the dirtyFields. As a consequence also the SaveButton is enabled.

I am not sure if I should open separate issue or just comment in this issue. so I will start with a comment and maybe separate it if needed.

I am facing relatively same inconveniences with ArrayInput and dirty behaviour. in my case, I am using zod resolver.

What you were expecting:

1. the form is not dirty
2. clicking the plus button adds an element and makes the form dirty
3. clicking the save button (without properly filling the inputs) the form should report the errors and the save button should stay enabled (as the array input still has an element added and the logic of save button rely on dirty state not validation state)
4. properly fill the input and click save should successfully submit the form

What happened instead:

react-admin-react-hook-form-isDirty-issue.mp4

Steps to reproduce:

here are the two stackblitz that reproduces the two behaviours
on the right side (browser) navigate to /#/posts/create

• old-working (with react-hook-form 7.50.1)
• broken (with latest react-hook-form)
  there is no difference between the two repo other than the resolution key in the package.json

Other information:
note that I fixed the react-hook-form version to 7.50.1 as the next release 7.51.0 is the one that introduced my issue

I think this issue on react-hook-form side is related
