Describe the question?

First of all, I wanted to thank you for creating this awesome library. I created a project a few months earlier, leave it there, and now that I came back to do some updates I’m amazed by the huge progress this library has made.

I’m not sure if this is a bug or it’s by design, and I couldn’t find any other issue for this specific problem.

When calling reset on the form to set a new state for the inputs, I’ve notice that the array field inputs doesn’t behave as any other regular input. Regular inputs update their value automatically, but for field arrays you have to use defaultValue={field.value} in order to get it to update. I was hoping those field could behave just as the rest would.

To Reproduce Steps to reproduce the behavior:

1. Go to code sandbox
2. Click on ‘reset values’ button

The field array get’s populated with two inputs, as defined by the object passed to reset, but their values are empty. The regular input outside the array works as expected.

Thank you for quick answer - right - it works, didn’t get that we were talking about ‘defaultValue’ in input field (focusing on defaultValue in useFrom()). Yet, I still having problem with my code and Material UI TextField component - trying to reproduce - I will post it today.
