EJB and CDI inject points in @FacesValidator and @FacesConverter fail to work by means of OmniFaces in newer versions of JSF

Question

I was using,

• Mojarra 2.3.0-m01
• OmniFaces 2.0.
• PrimeFaces 5.1 final
• PrimeFaces Extension 3.0.0
• GlassFish Server 4.1

And other Java EE artifacts.

Injection points in @FacesValidator like as follows,

@FacesValidator(value="testValidator")
public class TestValidator implements Validator {

    @Inject
    private DemoEJB ejb;

    @Inject
    private ManagedBean managedBean;

    @Override
    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException {
        // Use the injected EJB and/or managed bean here.
    }
}

Those injection points remain null (I did not explicitly try injecting an EJB but it should not happen as well like a managed bean).

Since the above-mentioned Mojarra version is still available as a snapshot, I tried downgrading it to 2.2.10 with the same version of OmniFaces which is 2.0 (alternatively also tried with OmniFaces 2.1-SNAPSHOT - on both Mojarra 2.2.10 and 2.3.0-m01 alternatively) but to no avail.

This worked, when I downgraded Majarra to 2.2.8-02 (tried with OmniFaces 1.8.1, 2.0 and 2.1-SNAPSHOT alternatively). I did not try other Mojarra versions.

Was the support to make @FacesValidator and @FacesConverter candidates for EJB and CDI injection points by means of OmniFaces (which in turn does not require any addition dependencies and/or configurations) removed for newer versions of Mojarra?

_{I have not yet explicitly tried in @FacesConverter just because changing this many libraries alternatively so many times using a buggy NetBeans IDE which also goes very slow on Windows by nature took the whole day from dawn to dusk.}

Answer 1

This is caused by a change in Mojarra 2.2.9. It works fine in 2.2.8. I reproduced it in both GlassFish 4.1 and WildFly 8.2. After scanning all issues listed in the 2.2.9 release notes and the associated change bundles, it appears to be the consequence of backport of issue 3552 to JSF 2.2.x. They internally disabled checking injectability of components, behaviors, validators and converters which implicitly registered them as CDI managed bean candidates. In other words, during 2.2.x until 2.2.9, Mojarra unintentionally offered "native" @Inject support in the mentioned artifacts.

In order to get injection in @FacesConverter and @FacesValidator to work anyway via OmniFaces, you need to add an empty /WEB-INF/beans.xml or at least one with bean-discovery-mode set to all instead of annotated.

<?xml version="1.0" encoding="UTF-8"?>
<beans 
    xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:weld="http://jboss.org/schema/weld/beans"
    bean-discovery-mode="all"
>
    <!-- ... -->
</beans>

It's the default value already, you could also just omit the bean-discovery-mode attribute.

The technical difference is that bean-discovery-mode="all" will register all eligible classes as CDI managed beans, while bean-discovery-mode="annotated" only registers classes with an explicit CDI scope annotation such as @RequestScoped as CDI managed beans, which would thus fail for @FacesConverter and @FacesValidator.
