Validation on a collection as a Group

[greghawk]

Not sure how to ask this or if I am being ignorant but I am attempting work on a collection that has overall group level validation. Think file uploader. I have valid and invalid files going into a collection and I need to track them as valid and invalid and have a group level validation accepted files count > X. When i attempt to call change on user.uploads versus user.uploads[ i ] I get mixed results. sometimes it works, sometimes it adds nested props to each prop like valid = {validating: false, valid: true, pristine: false} rather than valid = true
