org.omnifaces.cdi.validator.ValidatorManager
@ApplicationScoped public class ValidatorManager extends Object

The @FacesValidator is by default not eligible for dependency injection by @Inject nor @EJB. It that only when the managed=true attribute is set. But this doesn't support setting custom attributes. OmniFaces solves this by implicitly making all FacesValidator instances eligible for dependency injection without any further modification. In order to utilize OmniFaces managed validator, simply remove the Faces native managed=true attribute.

The ValidatorManager provides access to all FacesValidator annotated Validator instances which are made eligible for CDI.

bean-discovery-mode

Since CDI 1.1, when having a CDI 1.1 compatible beans.xml, by default only classes with an explicit CDI managed bean scope annotation will be registered for dependency injection support. In order to cover FacesValidator annotated classes as well, you need to explicitly set bean-discovery-mode="all" attribute in beans.xml. If you want to keep the default of bean-discovery-mode="annotated", then you need to add Dependent annotation to the validator class.

AmbiguousResolutionException

In case you have a FacesValidator annotated class extending another FacesValidator annotated class which in turn extends a standard validator, then you may with bean-discovery-mode="all" face an AmbiguousResolutionException. This can be solved by placing Specializes annotation on the subclass.

@FacesValidator(managed=true) compatibility

When the validator is managed with the managed=true attribute set on the FacesValidator annotation, then the validator won't be managed by OmniFaces and will continue to work fine for Faces. But the <o:validator> tag won't be able to set attributes on it.
