Ember ValidationProxy object

The intention

To have model data be dispayed in a form, which can be validated.

Usage

model: Ember.Object.create({
	name: 'Fred'
}),
form: validationProxy('model', {
    presence: true
})

Example

See the IndexController and template for an example.

Overview

1. form is bound to the inputs, leaving model alone.
2. The user can alter the form data, leaving model alone.
3. The user submits the form
4. The form is validated
5. If validation is successful, the changes are transfered to the model itself.

This works fine, apart from an inconsistancy I noticed with htmlbars not adding a classname to the input when in an error state.

Notice in the screenshot bind-attr is displaying an error but htmlbars is not:

Instructions for demo
