Validation for Reference field

[lukemarsh]

I have a creationView which has a few fields and a Reference.

For fields I know you can write validation like this:

new Field('name')
.validation({ required: true})

But when I do the same for Reference, the error message only displays in a modal with the message "invalid form"

new Reference('status_id')
.label('Status')
.targetEntity(status)
.targetField(new Field('name').map(truncate))
.validation({required: true}),

How can I change this validation to include a message or add a class to the field when there in an error?
