Quick work around: use object instead of primitive values for v-model

By the way, using v-model on primitive values inside an array looks weird to me... and I'm really surprised that it worked in 1.0.

@fnlctrl
Thanks for filling information! Actually I think weird to use v-model to the primitive value in the array too.
But in v2.0, we can use v-model for custom components and it would be nice to bind iterated model objects directly.

<ul class="my-list">
  <li v-for="item in list">
    <item-preview :value="item"></item-preview>
    <item-edit-form v-model="item"></item-edit-form>
  </li>
</ul>

This is a wontfix in 2.0 (and a breaking change from 1.x).

The recommendation is obviously using an array of objects instead.

OK I see, thank you for your description!
