React-final-form: How to validate and set errors in array fields ?

[kavink]

Any tips on how to Validate array form elements ? And how do I show error in each of Array element ?

e.g. from the example sandbox for arrays, if array element is added is it required or supposed to be an int.

The errors object has to correspond to the shape of the values object. e.g. If you have a field called addresses[2].street, the value for that field will be values.addresses[2].street and the error needs to be accessible from errors.addresses[2].street. Does that clear anything up? If not, provide a more concrete example and I'll try to help further.

@erikras would it be possible to add validation/error for example for Field Arrays in README : https://codesandbox.io/s/kx8qv67nk5 ?

Just want a reference, I tried locally to add assertions I had to do a basically create an empty array and then push objects into it. Would love to see best practice.

I plan to. Just haven't gotten around to it yet.

@erikras if you could please give me guidance on what kind of validation we'd like to demo (form/field level) I can give this one a shot 😎

@maciejmyslinski Could you please make an example for a form level validation? There is already an example for field level validation https://codesandbox.io/s/43x51p3q2w.

Any updates? Can someone make an example if it works already? I mean form-level array field validation
