Trying to find a way to resubmit a form with a model that has become invalid. The transaction cannot be reused and the dirty model cannot be moved to another transaction since it is dirty.

gistfile1.coffee

becameInvalid: ->
  @get('transaction').remove(this)
  transaction = App.store.transaction()
  transaction.add(this) # => Uncaught Error: assertion failed: Once a record has changed, you cannot move it into a different transaction
