after filtering Empty rows blank rows displayed while paging in the datatable using Primefaces

Question

I have problem with datatable using Primefaces 2.2.1 and JSF 2.0.

I have used filtering and paging in the datatable. When I try to filter the selected data is displayed and when i remove the filter the entire data is displayed. But after this when i try to use paging then suddendly all the rows becomes blank(empty) See screenshot below

enter image description here

Any suggestions. Please help.

I encountered the same problem and eventually discovered it was caused by my value object (in this case your user object) not implementing Serializable.

I'm pretty sure that this known issue has been resolved in both the 2.2.RC and the 2.2 final. I suggest updating your jar file.

Thanks for your reply. but i m already using primefaces-2.2.1.jar which is available on the primefaces website. Have you got any other web urls links to get to "the 2.2.RC and the 2.2 final". Please suggest. – user617966 Feb 21 '11 at 09:43
Nope, your correct, that's the most recent release according their site. You may want to try the PrimeFaces support forum, or report this as a bug to PrimeFaces. – Sean Feb 21 '11 at 16:17
Yes. I have reported it in the PrimeFaces but still no luck. http://primefaces.prime.com.tr/forum/viewtopic.php?t=7931 – user617966 Feb 21 '11 at 17:47
