JSF ViewState does not update when submitting 2 forms

I have a problem with JSF 2. I am using Mojarra 2.1.14 with Primefaces 3.1.4

I have a page with two forms: formA and formB . Two forms contain each ViewState view in a hidden input field.

<h:form id="formA" binding="#{sessionBean.formA}">
    <h:commandButton value="formA" action="#{sessionBean.actionA}">
        <f:ajax/>
    </h:commandButton>
</h:form>

<h:form id="formB" binding="#{sessionBean.formB}">
    <h:commandButton value="formB" action="#{sessionBean.actionB}">
        <f:ajax/>
    </h:commandButton>
</h:form>

The user submits formA using an Ajax action. Inside the Java action, I explicitly update formA and formB (which are bound).

public void actionA(){
    FacesContext.getCurrentInstance().getPartialViewContext().getRenderIds().add(formA.getClientId());
    FacesContext.getCurrentInstance().getPartialViewContext().getRenderIds().add(formB.getClientId());
    System.out.println("action A!!");
}

public void actionB(){
    System.out.println("action B!!");
}

Ajax answers have HTML code for formA and formB (element) and ViewState.

JSF HTML formA formB ViewState : formA. formB ViewState.

formB Ajax. ViewState , postBack , renderResponse true RESTORE, INVOKE APPLICATION: . VIEW_STATE, sumbit formB, .

JSF 2? - ?
