                <p:tab title="TODAS">
                </p:tab>
            </p:tabView>
        </h:form>
    </ui:define>
</ui:composition>
</html>

What happens is this:

My p:messages works perfectly when it is below the p:tab there in the update of p:commandButton i refer you by id. But in the above scenario it doesn’t work, that is, the message is not displayed on the screen. Does anyone know if this is possible? My update is wrong ?

try putting the <p:messages> as the direct daughter of <h:form>. As it is I believe that your message will never be displayed, because (if I’m not mistaken) <p:tabView> can only have <p:tab> as daughters.

Tab is a JSF container If p:commandButton is inside the tab and p:messages is outside, you should not update the whole way. E.g. :listNext:messages

From what I could notice, except for lack of knowledge on my part, between tabview and tab really does not work.

Try to leave it outside the tab by leaving the globalOnly = "false"

<p:messages id="messages" showDetail="true" autoUpdate="true" closable="false" globalOnly="false" />
<p:tabView id="viewFull">
        <p:tab title="PENDENTES">
         ...
         <p:commandButton value="Cadastrar"  update="cadastro,:listaEncomendas:messages" />

Or inside the desired Tab.

<p:tabView id="viewFull">
        <p:tab title="PENDENTES">
             <p:messages id="messages" showDetail="true" autoUpdate="true" closable="false" globalOnly="false" />
              ...
             <p:commandButton value="Cadastrar"  update="cadastro,:listaEncomendas:viewFull:messages" />
