Error on save new orders in backend

Even after fix some errors (pull request #28), I still getting this error messages when trying to save a new order through the admin panel: https://imagebin.ca/v/3f8kePPT9jBI

array (size=3)
  0 => 
    object(stdClass)[629]
      public 'code' => string 'CUS-001' (length=7)
      public 'path' => string 'customer.ownIdNotBlank' (length=22)
      public 'description' => string 'O identificador próprio não foi informado' (length=43)

      public 'description' => string 'O e-mail não foi informado' (length=27)

    object(stdClass)[626]

      public 'path' => string 'ownId' (length=5)
      public 'description' => string 'É necessario informar seu identificador próprio' (length=49)

Already checked module settings on System->Settings->Payment methods, but without success (only found the message that this feature still in beta)

I've found that this is related to the same cause of #25, where suggests this video with a workaround: https://www.youtube.com/watch?v=1Lep1ol4gVk Great to see an alternative, but will be good to get this working with native Magento methods
