FieldArray's unshift mutator does not update state correctly

Bug

What is the current behavior?

When using the unshift mutator to add an item to the beginning of an array, the touched state from the item previously at index zero (if one exists) is maintained.

What is the expected behavior?

I would expect the item that was added to the beginning of the array to have a touched state of false.

Hello,

If it can help for further investigation, I think it might be related to #33

I have a similar issue. I am noticing that the meta associated with a field is not moved with the input values. So, when you move things around with mutators, the input is moved, but is then associated with the meta from whatever previously existed at the new index.

This is particular problematic with Drag-and-drop. My field moves, but the meta, which includes things like dirty, pristine, touched, valid, etc, all stay associated with the wrong input values.

this should be resolved in [email protected]

@311chaos sweet, I'll try it out and report back.

No. This is not resolved. In fact, my [email protected] fix mistakenly assumed that that sort of movement was the only problem, but unshift is a different beast. ⚠️ Still in progress.... ⚠️
