watch method using useFormContext()

[fabiendeborde]

I am sorry if this is a dumb question, but I expected watch to watch an input for any changes it gets but it seems it only works if tis input only is changed. If I update a different input in the same form I lose the watch effect.

import React from 'react'
import { useFormContext } from 'react-hook-form'

const PropertyOwnerInfo = () => {
  const { watch } = useFormContext()
  const enabled = watch('property_enabled')
  console.log('enabled', enabled)
  return (
    <div></div>
  )
}

export default PropertyOwnerInfo

I have a form in another component with a few inputs.
If i touch only property_enabled watch is working as expected, if I touch another component it stops working.
Am i misunderstanding the way to use watch?

if I touch another component it stops working.

what do you mean?

I am sorry, my explanation was probably incomplete.
I f I change property_name and then change property_enabled, the constant enabled is not updated.
The watch "effect" stops when any other inputs change.

that's not expected, do you have a codesandbox?

[fabiendeborde]

I am going to try to create one as soon as I can.

I created a small simplified sample here : https://codesandbox.io/s/muddy-sound-gl47z
and its is working....
I guess the problem comes from the logic I inserted around the inputs and the form...

Thanks a lot for your quick answers! I am going to try to debug this during the weekend, if I find the origin of the problem I'll post here my solution.

Please submit an isolated/small codesandbox, it helps me to investigate the problem or potential bug.

I finally identified why the form was stopping watching my input.
My form was wrapped in a parent container with no access to the form context and was preventing the rerender...

Thanks a lot for your answers, and for asking me to use codesandbox, it really helped me isolating the issue!
By the way, react-hook-form is awesome, keep up this great work!!
