Re: Pagination of large database tables

[Paul Iov]

Thanks Mohammad, but i don't think, it meets all of my needs :) I'm using A4j/Facelets to provide flexible and CONSISTENT templating support to the customers. It would be really strange to make some exception just because one of used UIComponents don't work correctly. The problem with t:dataScroller is that it generates duplicated/inconsistent IDs if the underlying DataModel changes. So I've extended the ac:AjaxDataScroller by Adrian Mitev to support events and it works fine. I think, one custom UIComponent, which does exactly what it have to do is much better than one, which provides "workaround" for some other. regards, paul Hello But if you use PPRPanelGroup of Tomahawk Sandbox components you can add Ajax-support to your page easily and it work woth dataScroller perfectly On 2/19/07, Paul Iov <[EMAIL PROTECTED]> wrote: Hi Pallavi! First of all take a look at http://wiki.apache.org/myfaces/WorkingWithLargeTables. The illustrating code there is IMHO a little bit buggy (especially for subsets of large datasets, which commes from EJB it makes no sense to fetch the same page twice, since the sorting order never chahges), but generally this approach works fine. I have exactly the same usecase - large resultsets and fetching on demand, but I'm using ac:AjaxDataScroller insteed of <t:dataScroller>, because the second one is not Ajax-compatible :( Any way, with own extended implementation of DataModel im background it would be preaty easy to implement "fetch more" feature, you are asking for. regards, paul [EMAIL PROTECTED] schrieb: Hi All,   I currently have a requirement for pagination. I want the following GUI display <<1 2 3 4 5 more >>. Where on click of << is for previous. And on click of >> is for next. So with these two i could go ahead with <t:dataScroller> for the above mentioned functionlity. But if i had the advantage of knowing the total number of rows with DB to perform COUNT operation on the total number of rows.   But for larger tables this wouldn't be efficient. Hence the requirement demands fetching rows in multiples of 250. And each page displaying 50 rows per page. With the click on more it would fetch the next 250 rows. And the display should look like << 6 7 8 9 10 More >>.(something similar to google's pagination).   Is there a way by which i can implement this. Or can i extend the functionality of <t:dataScroller> to implement this.
