Hi,
I tried to create a tabular listing with pagination completely from scratch
using only ListView-s and you can look at the code here:
http://fisheye3.cenqua.com/browse/j-trac/trunk/jtrac/src/main/java/info/jtrac/wicket/ItemListPanel.java?r=946
It's not Ajax, but may help as a reference. The pagination code is lines 75
- 167
HTML code is here:
http://fisheye3.cenqua.com/browse/j-trac/trunk/jtrac/src/main/java/info/jtrac/wicket/ItemListPanel.html?r=962
Regards,
Peter.

Thanks for the answer. Hmmm but my last question wasn't clearly quite
answered :)
Actually I was asking for a sample code of AjaxPagingNavigationLink/
AjaxPagingNavigationIncrementLink with AjaxPagingNavigationBehaviour as I
had a difficult time in finding and understanding the correlations between
them. My goal is to move away the default << 1 2 ..n >> paging display in
AjaxPagingNavigator to a more customized paging display. This explains the
reason behind my attempt on the usage of AjaxPagingNavigationLink/
AjaxPagingNavigationIncrementLink with AjaxPagingNavigationBehaviour. But
I
don't know where to begin and what I'm missing now. A sample skeleton code
will greatly help me to understand the correlation here. :) Any helps for
me
on this?
