The following data table signature causes problems:

<p:dataTable value="#{Employee.listEmployee}" var="e" scrollable=" height="300" selectionMode="single" scrollable="true" rows="20" liveScroll="true">...</p:dataTable>

When you use datatable like this, then only first 20 of rows works as expected (or X rows if you put rows=X). Data is shown ok, but any link, button or other component placed inside one of datatable's columns doesn't work after scrolling over X rows. When I scroll to 30th, or 50th or whatever is larger then this X rows: links, buttons, live editing just stops working.

I'm using JSF Mojarra 2.0.3, Primefaces 2.2 M1, Facelets. Application is run on Glassfish 3.0.1.

By the way, this issue has been discussed on forum:

Anyone has seen this ticket??? Any news on this?

Any news? When this issue will be fixed?

I have similar problem

Table with live scrolling is quite useless if this bug remains in future. Hope that someone out there will notice this issue!

I have the same problem! Table is useless!

I must add here since I have no reply on original post: data table live scroling isn't working at all! It only works if you have plain data with no links. If you put link in some column or command button it just won't pas any parameters trough f:attribute.

I created this issue 3-4 months ago, but nobody from primefaces replies a long time now! Please notice this! Live scrolling is really great feature but useless currently.

Yes, I agree totally unusable.

I'm at one with Comment 8 by sal...@gmail.com, Jan 20. It would be a great feature if it works good. Please make it better.

2.2 is about to be released, and nothing yet on this issue. Any chances we enjoy this feature soon?

This would solve many problems in the papers ....

Live scrolling is great feature, if it works properly, of course. So, is there any chance, that this issue will be fixed in 2.2 final release?

I would agree that with this bug live scrolling is almost useless.

I made another post on forum, mailed Cagatay and he said they can give it high priority and make sure it will be in 3.0.M1, even do it is not planned.

Hi, I maanged to resolve this issue. I modified the org.primefaces.component.datatable.DataTableRenderer a bit. Here is the link in the forum: http://primefaces.prime.com.tr/forum/viewtopic.php?f=3&t=8234&p=38007#p38007

I made a patch too, but I can't seem to attach it.

Taking ownership.

Fixed by adding scrollRows option. Use this one instead of rows attribute for livescrolling.

Finally!!! Great!
