This pull request helps in the situations where the ACO object's do not have "id" has primaryKey field.
See issue #18

Thanks for the pull request.

1/ Could you clean your patch not to fix all those whitespace issues? Ideally this should take place in another pull request as it could create unnecessary conflicts with other patches, and is not the right place to fix it.

2/ You are adding another $inherit = in the view rather than fixing the existing one.

3/ Indentation issue when setting aroPk to the view.

Many thanks!
Fred
