> Allow validator to set a custom failure message
> -----------------------------------------------
>
> Key: SLING-4010
> URL: https://issues.apache.org/jira/browse/SLING-4010
> Project: Sling
> Issue Type: Improvement
> Components: Validation
> Reporter: Konrad Windszus
> Assignee: Bertrand Delacretaz
> Labels: validation, validator
> Fix For: Validation 1.0.0
>
>
> Currently the Validator may only return a boolean value or an exception in
> case the validator was called with invalid parametrization
> (https://github.com/apache/sling/blob/trunk/contrib/validation/api/src/main/java/org/apache/sling/validation/api/Validator.java).
> In some cases the validator could give some important information about why
> the validation failed. This is e.g. the cause for a reference validator where
> the cause for a failed validation could be:
> # referenced resource is not existent
> # referenced resource is not having the right resource type
> # referenced resource is not activated
> So instead of only returning a boolean value, it should also be possible to
> return a failure message.
