Guys, I have a div that needs to be updated in 5s, but it’s giving error saying that the ID is not found. 

<h:form id="form">      
   <br />
   <center><h:outputLabel value="Visão Geral" class="titlePrincipal" /></center>

   <p:poll interval="#{controleBean.ciclo}" update="refreshArea" />
   <div id="refreshArea">
        <ui:repeat var="abr" value="#{controleBean.auxiliarbr}" varStatus="status">
            <div class="containerBomba" title="Descrição">
                <div class="reservatorio reservatorio#{controleBean.verificarNivelReservatorio()}" title="Reservatório">
                    <h:outputText value="#{abr.reservatorio.nomeReservatorio} (#{controleBean.verificarNivelReservatorio()}%)" />
                </div>

                <ui:repeat var="b" value="#{abr.bombas}" varStatus="status2">
                    <div class="bomba bomba#{controleBean.verificarEstadoBomba(b)}" title="Bomba">
                        <h:outputText value="#{controleBean.verificarNomeBomba(abr, b)}" />
                    </div> 
                </ui:repeat>
            </div>  
        </ui:repeat>
    </div>
</h:form>

I tried :form:refreshArea, but it didn’t work either.

Someone can help out?

    Try to put inside a p:panel or a h:panelGroup and tries to update by passing 'id do form':'id do container', where container will be the p:panel or the h:panelGroup.

    you will not be able to update non-jsf components. Replace your div with a jsf component. Complement: http://stackoverflow.com/a/13011934/5165064

The solution was just to change the div for p:panel.
