If you want to do this.You can't use the url in the p:menuitem because we must call a method to changing the tabindex before skipping to the prefil.xhtml page. If you use the url, the method will be invoked after we skip to the prefil.xhtml page .

First, you can use the action field of the p:menuitem, the method returns the address you want to skip to:

<p:menubar autoSubmenuDisplay="true">  
    <p:submenu label="Perfil">  
        <p:menuitem value="Editar" action="#{some.editar}" ajax="false"/>  
        <p:menuitem value="Ver" action="#{some.ver}" ajax="false" />  
    </p:submenu>  
</p:menubar> 

These two method do something to change the tabindex like this:

public String editar() {
    tabindex = 0;
    return "verPerfil";
}

public String ver() {
    tabindex = 1;
    return "verPerfil";
}

Then the p:tabView has an attribute named activeIndex. It is the index of the active tab, its default value is 0. So you can do as follows:

<p:tabView dynamic="true" activeIndex="#{some.tabindex}" >
    <p:tab id="ver" title="Ver perfil">
        <ui:include src="verPerfil.xhtml" />
    </p:tab>
    <p:tab id="editar" title="Editar perfil">   
        <ui:include src="editarPerfil.xhtml" />
    </p:tab>
</p:tabView>

Then each menuitem will activate the corresponding tab.
