and changed the final onClick method to non-final. because AjaxOrderByLink have to override it. ( perhaps I should not do it this way)
And I added another ListSortStateLocator to wrapper a simple List as a ISortStateLocator, then PageableListView/ListView can use AjaxOrderByLink too .
The original example is like this:
SortableContactDataProvider dp = new SortableContactDataProvider();
final DataView dataView = new DataView("oir", dp)
......
datacontainer.add(new OrderByBorder("orderByFirstName", "firstName", dp)
{
protected void onSortChanged()
{
dataView.setCurrentPage(0);
}
});
now use ajax is as simple as this :
datacontainer.add(new AjaxOrderByBorder("orderByFirstName", "firstName", dp, dataView)
{
protected void onSortChanged()
{
dataView.setCurrentPage(0);
}
});
and also, to sort a PageableListView : // borrowed by PageablePage example
WebMarkupContainer datacontainer = new WebMarkupContainer("data");
datacontainer.setOutputMarkupId(true);
add(datacontainer);
final List list = Arrays.asList(names);
ISortStateLocator ssl = new ListSortStateLocator(list){
protected void sortList(List list,String name, int order){
// because I'm lazy, here I just reverse the list.
Collections.reverse(list);
}
};
final PageableListView listview = new PageableListView("rows", list, 10)
{
protected void populateItem(ListItem item)
{
item.add(new Label("name", item.getModelObjectAsString()));
}
};
datacontainer.add(listview);
datacontainer.add(new AjaxOrderByBorder("orderByName", "name", ssl, listview)
{
protected void onSortChanged()
{
listview.setCurrentPage(0);
}
});

i checked this into 2.0 trunk earlier today, but im having trouble backporting to 1.2
see DefaultAjaxFallbackDatatable
only supports sorting so far, when i have time i will take a look at your paging patch.

this is a bit of work and i dont know if someone has the time to do it right now.
you can either create a bug for it and we will get to it when we can, or do the refactor yourself and provide us with a patch.
i know martijn is interested in working on this but i am unsure about his availability.
