Incorrect inputs and outputs processing

Hi Denis, so did you see "value: { get_property: [ authorization_form, auth_url ] }" (i.e. the second value) as an output? I would vote for one of these:
1. Display the last output value? i.e. in this case, display:
    auth_token:
      value: { get_property: [ authorization_form, auth_url ] }
This is how 'OpenStack Heat' is working, that it respects last duplicated name and a similar approach should be fine for us.
2. Throw validation error that 'duplicate names are not allowed.

Hello.

I'm fine with validation error on duplication.

Kind regards,
Denys Makogon

Hi All,

As an user I prefer to throw validation error that 'duplicate names are not allowed. It helps to avoid errors where you do not get the expected results.

So the inputs face a similar problem, it should also throw the same validation error.

Thanks Denis and Miguel. I have changed bug subject to fail validation for duplicate inputs and outputs.
