REMINDER: Apache EU Roadshow 2018 in Berlin is less than 2 weeks away!
Hello Apache Supporters and Enthusiasts This is a reminder that our Apache EU Roadshow in Berlin is less than two weeks away and we need your help to spread the word. Please let your work colleagues, friends and anyone interested in any attending know about our Apache EU Roadshow event. We have a great schedule including tracks on Apache Tomcat, Apache Http Server, Microservices, Internet of Things (IoT) and Cloud Technologies. You can find more details at the link below: https://s.apache.org/0hnG Ticket prices will be going up on 8^th June 2018, so please make sure that you register soon if you want to beat the price increase. https://foss-backstage.de/tickets Remember that registering for the Apache EU Roadshow also gives you access to FOSS Backstage so you can attend any talks and workshops from both conferences. And don’t forget that our Apache Lounge will be open throughout the whole conference as a place to meet up, hack and relax. We look forward to seeing you in Berlin! Thanks Sharan Foga, VP Apache Community Development http://apachecon.com/ @apachecon PLEASE NOTE: You are receiving this message because you are subscribed to a user@ or dev@ list of one or more Apache Software Foundation projects.
Re: Paint UI before starting long running tasked
I did used a nasty way by using AjaxLazyLoadPanel and providing my custom
loading as both - lazy load component (with code in renderHead) and loading
component (empty renderHead) . Not the most elegant way but from user point
of view its ideal :)

You will need to create a custom Panel to do all this.
I guess you can still use AjaxLazyLoadPanel if you use Java WebSocket
client, but this is something you have to decide.

Re: How to use language/locale from url without creating a session?
Thank you, Martin! That’s an interesting way to fix this. Didn’t think of that, and it fits quite well with our current code, too. We can put our own “requestedLocale” field in our WebSession subclass, and use that if the session is temporary. Thanks!

Re: wicketstuff datatabes /jQuery Datatables
Hi, Please check the example. https://github.com/wicketstuff/core/blob/1fa257603ed918d54a32f0e92bd949aa86afb65c/datatables-parent/datatables-examples/src/main/java/org/wicketstuff/datatables/demo/infiniteScroll/VirtualScrollDemoResourceReference.java#L38 Here you can use the page parameters to filter out or paginate the result.

Hi, I'm using DemoDatatable in wicketstuff package to develop a table with fair amount of data (>= 10,000 rows) to display. Can anyone point me to the right direction as how to implement this with server side processing? I've already implemented a SortableDataProvider, but I am not too sure how to invoke it in my program. -- Sent from: http://apache-wicket.1842946.n4.nabble.com/Users-forum-f1842947.html - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Hi, I'm using DemoDatatable in wicketstuff package to develop a table with large amount of data (>= 10,000 rows) to display. Can anyone point me to the right direction as how to implement server side processing? I've already implemented a SortableDataProvider, but I am not too sure how to invoke it in my program. -- Sent from: http://apache-wicket.1842946.n4.nabble.com/Users-forum-f1842947.html - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
