FacesContext not injectable in Wildfly 14 with JSF 2.3 (Mojarra, main module)

Question

I have a bean:

import javax.faces.context.FacesContext;
import javax.faces.view.ViewScoped;

...

@Named
@ViewScoped
public class SimpleBean implements Serializable
{
    private static final long serialVersionUID = 1L;

    @Inject
    protected FacesContext facesContext;

    ...
}

According to

https://arjan-tijms.omnifaces.org/p/jsf-23.html#1316

this should work with 2.3 ...

When deploying to Wildfly 14, this results in:

My faces-config.xml is:

<?xml version="1.0" encoding="UTF-8"?>
<faces-config xmlns="http://xmlns.jcp.org/xml/ns/javaee"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_3.xsd"
              version="2.3">
    ...

QUESTION:

What's wrong here and how do you solve this?

BTW the answer here didn't solve it: How to inject FacesContext with JSF 2.3 and TomEE?

Answer 1

According to

https://github.com/javaserverfaces/mojarra#activating-cdi-in-jsf-23

this is the answer:

By default, JSF 2.3 will run in JSF 2.2 modus as to CDI support. Even when you use a JSF 2.3 compatible faces-config.xml. In other words, the new JSF 2.3 feature of injection and EL resolving of JSF artifacts (spec issue 1316) won't work until you explicitly activate this. In other words, @Inject FacesContext doesn't work by default. This is necessary in order for JSF 2.3 to be fully backwards compatible.

There is currently only one way to activate CDI in JSF 2.3 and herewith make JSF 2.3 to run in full JSF 2.3 modus. Put the @FacesConfig annotation on an arbitrary CDI managed bean. For example, a general startup/configuration bean.

@FacesConfig
@ApplicationScoped
public class YourApplicationConfig {
    // ...
}

Full example:

import javax.enterprise.context.ApplicationScoped;
import javax.faces.annotation.FacesConfig;

@FacesConfig
@ApplicationScoped
public class Jsf23Activator {
    // ...
}

You need the @ApplicationScoped annotation or it will not work. After that in my startup the console finally displays:
