use the attribute first

cheers

Hi venuvanama,

which version of richfaces are you using? Because I saw in your code that you are using this attribute "scrollToTop" that doesn't exists on component attributes description as you can see in

http://livedemo.exadel.com/richfaces-demo/richfaces/scrollableDataTable.jsf?tab=info&cid=297379 at least not in this version that I'm looking.

Maybe this could be causing the problem

and just for test try to use first="0"

let me know what happended!

Best regards,

Jorge

Well, I've looked in the Jira database for this component and something related with your issue and I found this:

https://issues.jboss.org/browse/RF-2106

Maybe you are right some bug related with your version!

So, consider update your richfaces version and try again!

Jorge.

Hi Venu,

I've implemented the richfaces exadel example and works fine here!

I'm using richfaces 3.3.3.final

here is the code:

MBean:

import java.math.BigDecimal;

import java.util.ArrayList;

import java.util.Arrays;

import java.util.List;

import java.util.Random;
