Validation error of structs with integer constants.

[aaronn]

For whatever reason, validating integer constants fails when the value is 0. The following returns with "Code" is required (or something similar). If I change my constants to 1,2 instead of 0,1 it works fine, and if it change OK to NOT_OK in the example (keeping 0,1) below it works fine too.

type ResponseCode int

const (
    OK ResponseCode = 0
     NOT_OK ResponseCode = 1
)

type data struct {
    code: OK,
    something: "foo"
}

func (d Data) Validate() error {
    validation.ValidateStruct(&d, 
        validation.Field(&d.code, validation.Required),
    )
}

Nevermind, I found the Required vs NotNil section.
