DataTable Filter and Current Page

[martinezjavier]

Hello I have two questions about the DataTable component.

1- How can I get the page number that my data table is showing. I have a page were the user can Generate two PDF from the data "Current Page" and "All". Im using JasperReports to generate the PDF, not the Data exporter so I have to ask the model the "current page" info.

I tried this

private DataTable dataTable;

binding="#{peopleController.dataTable}"

int currentPage = tablaPersonas.getPage();

But it always return 1 regarding wich page is showing the data table.

2- In the PDF documentation at the dataTable section it says that the data table supports a "global filter". According the docs, I defined

<h:inputText onkeyup="list.filter(this.value);" styleClass="myfilter"/>

<p:dataTable .... widgetVar="list">

<p:column filter="true">

But filter doesn't seems to be a valid attribute anymore (Im using yesterday nigthly build primefaces-2.0.0-SNAPSHOT.jar)

Algo tried

<p:column styleClass="myfilter">

But It didn't work either.

Does the new dataTable component supports global filter or only column scoped filters?

Thank you very much

Hi,

1) DataTable has a new api called getPage()

2) We had to global filter for now after recent filtering enhancements. But it's not permanent and will be reenabled soon.

Thanks Cagatay,

In my previous post I said that I did try:

int currentPage = tablaPersonas.getPage();

But it always returns 1 no matter what page is showing the data table.

This is strange as I use getPage with no problems. Can you try with latest snapshot, nightly builds were broken since a couple of days but they're now back live.

I'm using the latest snapshot but having a null reference pointer exception.

The same code is working well with previous snapshot

<p:dataTable value="#{personaListadoController.listaPersonas}"
var="persona"
rendered="#{!empty personaListadoController.listaPersonas}"
paginator="true"
paginatorTemplate="{FirstPageLink}{PreviousPageLink}{PageLinks}{NextPageLink}{LastPageLink}{RowsPerPageDropdown}"
firstPageLinkLabel="#{i18n.inicioPaginador}"
lastPageLinkLabel="#{i18n.finPaginador}"
nextPageLinkLabel="#{i18n.siguientePagina}"
previousPageLinkLabel="#{i18n.paginaAnteior}"
rows="10"
rowsPerPageTemplate="10,15,20"
widgetVar="lista"
binding="#{personaListadoController.tablaPersonas}">
