Hi Igor,
Thanks for the reply. I had a look at the phonebook example application in
wicket-stuff.
I have a question?
1. Currently it does not maintain the checked(or selected) items if you
change the datatable's pages. How can I add that feature?
2. Can I replace CheckBox with AjaxCheckBox and DataTable with
AjaxFallBackDataTable ?
Thanks,
Rachit
