tabChange event on primefaces tabView doesn't set values in ManagedBean

I am facing a problem using primefaces 5.0 and jsf 2.2.5. Using a p:tabView with two tabs sharing the same ManagedBean and the same object the event tabChange is not working as expected. When user change the tab I want to execute the same validation as if he had clicked the button, but the event is not refreshing the bean values, however the values are being posted. I was able to reproduce the problem with this simple example. xhtml code: 

<h:body>
    <div class="well">
        <h:form id="testeForm">
            <p:tabView id="tView">
                <p:ajax event="tabChange" 
                        process="@this" 
                        update="@form"
                        listener="#{testeBean.onTabChange}" />
                <p:tab id="tab1" title="tab1">
                    <p:inputText id="teste1" 
                                 value="#{testeBean.evento.nome}" />
                    <p:commandButton id="savetab1" 
                                     process="tab1" 
                                     update="@form"
                                     actionListener="#{testeBean.saveTab1}" 
                                     value="salvarTab1">
                    </p:commandButton>
                </p:tab>
                <p:tab id="tab2" title="tab2">
                    <p:inputText id="teste2" 
                                 value="#{testeBean.evento.descricao}" />
                    <p:commandButton id="savetab2" 
                                     process="tab2" 
                                     update="@form"
                                     actionListener="#{testeBean.saveTab2}" 
                                     value="salvarTab2">
                    </p:commandButton>
                </p:tab>
            </p:tabView>
        </h:form>
    </div>
</h:body>

ManagedBean:

package com.example.bean;
@ViewScoped
@ManagedBean(name = "testeBean")
@Getter
@Setter
public class TesteBean {

private Evento evento;

@PostConstruct
public void init() {
    evento = new Evento();
}
public void saveTab1() {
    System.out.println(evento);
}

public void saveTab2() {
    System.out.println(evento);
}

public void onTabChange(TabChangeEvent evt) throws LoundScreenException {
    System.out.println(evt.getTab().getId());
    System.out.println(evento);
}

}

The value being posted: inputText posted

I tried process="@this" process="@form" process="@all" immediate="true" without success. Am I missing something here? Thanks in advance.

Important Update:

After spent some time debugging primefaces code, in the class org.primefaces.component.api.UITabPanel I realize that Primefaces only processes child components in its process() methods if it is not the source of the ajax request:

if(isRequestSource(context)) {
   return;
}

So I remove this piece of code and recompile primefaces and now it works fine. I'll let this question open, just in case of someone more experienced than me find a better solution.

After primefaces 6.0

<p:ajax event="*" listener="*" skipChildren="false">

skipChildren="false"

helps, and set value to managed beans before listener's function call.
