Detailed Description

If the stash content identified by stashKey does not contain any of the values specified in the stashValues list, the field under validation must be present and not empty. This validator ist the opposite of ValidatorRequiredIfStash and is similar to ValidatorRequiredUnless.

Note

Unless validation is started with NoTrimming, whitespaces will be removed from the beginning and the end of the input value before validation. So, fields that only contain whitespaces will be treated as empty.
