JSF + Primefaces update component when switching pagination

Question

    <p:dataList paginator="true" value="{bean.lista}"
                        var="lista">
    </:dataList>

<h:outputText value="qualquerCoisa" id="teste"/>

How do I update outputText 'test' every time the dataList page changes? , example paging 1,2,3,4[...] when the user changes from page 1 to page 2 update the 'test' component, when to switch to another page update again? The component must be outside the dataList or datatable and has to be when changing pagination, without buttons or something like.

Answer 1

follows an example:

<p:dataTable var="variavel" paginator="true" rows="1" value="#{myBean.list}">
  <p:ajax event="page" update="buttons" listener="#{myBean.update}" />
  ...
</p:dataTable>

here’s the method that will update your guy:

public void update(PageEvent event) {
  int var = event.getPage();
  ...
  (aqui você atualiza a variavel do seu componente)
  ...
}
