Showing a problem when using ObjectController with ValidatorViewSupport

These commits show the problem that I was describing in issue #3. It turns out I was wrong about the cause (no problem with the latest version of ember or with using ember-data and ember-validation). The issue with  `ValidatorViewSupport` happens when you are using it along with an `ObjectController` as you can see if you try to use example 2 in my version of the code...

Is this something that can be worked around or should I bind the properties as `model.propertyName` rather than just `propertyName`?
