JSF2.2.1 + form binding + ViewScoped trouble

Question

I've the following JSF page to try either standard JSF2.2.1 and Primefaces4 CommandLink:

<h:form id="test3" binding="#{test3.hf}">
    <h:commandLink value="Test3" action="#{test3.print('PROVA.....')}" />
    <br />
    <p:commandLink value="PFtest" action="#{test3.print('PROVA.....')}" />
</h:form>

... and the relative ViewScoped managed bean:

@ManagedBean(name="test3")
@ViewScoped
public class Test3 implements Serializable {
    HtmlForm hf;    

    public Test3() {
        super();
    }

    public HtmlForm getHf() {
        return hf;
    }
    public void setHf(HtmlForm hf) {
        this.hf = hf;
    }

    public String print(String text) {
        System.out.println(text + " " + System.currentTimeMillis());
        System.out.println(hf.getChildren().size());
        return null;
    }

}

The strange behavior is that, clicking on one of two CommandLink, the print method is called two times !!!
The problem don't occurs if I avoid the form binding or I add an additional binding to CommandLink components.

What do you think about ? Thanks.
