Formsets by Ref

[bkotch]

In your documentation, you show managing the formsets by storing the constructed form in the state.

http://newforms.readthedocs.io/en/latest/formsets.html?highlight=formset

var ArticleFormSet = forms.FormSet.extend({form: Article})
var BookFormSet = forms.FormSet.extend({form: Book})

var PublicationManager = React.createClass({
  getInitialState: function() {
    return {
      articleFormset: new ArticleFormSet({prefix: 'articles'})
    , bookFormset: new BookFormSet({prefix: 'books'})
    }
  },

  // ...rendering implemented as normal...

  onSubmit: function(e) {
    e.preventDefault()
    var articlesValid = this.state.articleFormset.validate()
    var booksValid = this.state.bookFormset.validate()
    if (articlesValid && booksValid) {
      // Do something with cleanedData() on the formsets
    }
  }
})

Is there a way we can do it via ref so we can reference the formset later and just allow the formset to render when the props update?
