Re: PagingNavigator faster paging
Ì am not sure about Pagenavigator (is this an existing Wicket class? I can't find it). We have implemented what you describe using DataView and by implementing the IDataProvider to do the call to Hibernate with the given first and count passed in the method *Iterator iterator(int first, int count);* you need to implement. Hope this helps, Lars On Fri, May 16, 2008 at 1:47 PM, Mathias P.W Nilsson [EMAIL PROTECTED] wrote: Hi! I'm using a Pageable List view to list my items.

Don't use the PageableListView, but use DataView with an IDataProvider. Martijn On 5/16/08, Mathias P.W Nilsson [EMAIL PROTECTED] wrote: Hi! I'm using a Pageable List view to list my items.

Re: PagingNavigator faster paging
Thanks!
I used this but I don't think it is any faster
class ItemProvider implements IDataProvider{
private static final long serialVersionUID = 1L;
public Iterator iterator(int first, int count) {
return getItemDao().getItems(getFilters(), first, count
).iterator();
}
public int size() {
return getItemDao().getItemCount( getFilters());
}
public IModel model(Object object) {
return new Model((Item) object);
}
public void detach() {
// TODO Auto-generated method stub
}
}

Re: PagingNavigator faster paging
You can use PagingNavigation to page trough everything in the DB:
http://www.wicketstuff.org/wicket13/repeater/;jsessionid=1A8942B5B6C08E39348C4E8923DB32CB?wicket:bookmarkablePage=%3Aorg.apache.wicket.examples.repeater.PagingPage
That way you don't get everything from the database all the time.
Grtz,

Re: PagingNavigator faster paging
Yes, I use the page navigator. -- View this message in context: http://www.nabble.com/PagingNavigator-faster-paging-tp17272873p17274891.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: PagingNavigator faster paging
I was unclear with the class. I use PagingNavigation with my dataProvider but it's still to slow. Must be something else. -- View this message in context: http://www.nabble.com/PagingNavigator-faster-paging-tp17272873p17274937.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
