在p：dataTable中激活分页时？

Question

I am using primefaces 3.2

How can I know when the user is pushing one of the pagination button in p:dataTable ?

Thanks

If you need an ajax behaviour when user changes the page, you can use the following code:

<p:dataTable value="#{bean.collection}" var="obj" >
      <p:ajax event="page" update="componentsToUpdateOnPage" listener="#{bean.pageListener}" />
      <p:column>
         .. etc..
</p:dataTable>

If you are using a lazy loading data table, you have to override the load() method of LazyDataModel. that method is executed on page load, when page changes and also when you sort or filter the datatable.
