使用时销毁@ViewScoped @ManagedBean <h:link includeViewParams=“true”>

Question

I'm using Mojarra 2.2.12. I have a case where a @ViewScoped @ManagedBean is immediately destroyed on page load, although the view is not ended. The problem is reproducible with solely the below in <h:body> :

<h:outputText value="#{testBean.value}" />
<h:link outcome="other" includeViewParams="true">link</h:link>

The other must refer to a different view and not the same view. There's no <f:viewParam> necessary to reproduce the problem.

And the below bean:

import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;

@ManagedBean
@ViewScoped
public class TestBean implements Serializable {

    @PostConstruct
    public void init() {
        System.out.println("@PostConstruct on " + this);
    }

    @PreDestroy
    public void clear() {
        System.out.println("@PreDestroy on " + this);
    }

    public String getValue() {
        return "test";
    }

}

If we remove includeViewParams="true" attribute, then the bean is not immediately destroyed.Why does includeViewParams="true" cause this behavior?

Add this dependency to pom.xml, I was passed it.

<dependency>
    <groupId>javax.enterprise</groupId>
    <artifactId>cdi-api</artifactId>
    <version>1.2</version>
</dependency>
