Thank you Igor,
I've solved. I post the relevant part of the code that do the trick:
add(new AjaxFallbackLink(users_shuffle) {
@Override
public void onClick(AjaxRequestTarget target) {
Collections.shuffle(userColumns);
usersTable = new AjaxFallbackDefaultDataTable(users_table,
userColumns, userProvider, 20);
getParent().replace(usersTable);
if (target != null) {
target.addComponent(usersTable);
}
}
});

Re: Datatable columns converter
Hi Michael, thank you for your suggestion. what do you think about overriding the AbstractColumn#populateItem() to add a Label to the cellItem and setting up a proper IConverter to that component? bye alf Michael O'Cleirigh wrote: This question came up last week aswell, here is an example of how you to subclass PropertyColumn to convert an integer into an arbitrary string: http://www.nabble.com/Re%3A-How-to-manipulate-values-in-a-data-table--p23413680.html Essentially you wrap the PropertyModel with a custom IModel implementation that does the conversion you want (on each cell). Then you build the DataTable using your custom column implementation. -- View this message in context: http://www.nabble.com/Datatable-columns-converter-tp23502460p23519993.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Application scope vs Singleton
Hi James, I would like to know what is the difference between a Singleton class with a static accessor method and POJO stored into my WebApplication class (with proper getter). What is the preferred way to set an application scoped object?

Re: Application scope vs Singleton
Thank you to all for your precious suggestions. My question is not for a real need. Supposing to discard the injection strategy, I would like to know if the cache of an object into my WebApplication class during application startup has the same result if I make this object Singleton (and not store it in WebApplication). Can be some problems about thread-safety or other issue in one case rather than the other? I'm sorry if this seems to be a stupid question... alf -- View this message in context: http://www.nabble.com/Application-scope-vs-Singleton-tp23559402p23563036.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: user input lost on first form submission
igor.vaynberg wrote: are you sure the container is not interfering between you pressing the submit button and wicket processing the form input? Hi igor, thank you for your answer. The container redirect the user to a wicket page, the form in this page does not send user input on first submit (the onsubmit method is executed but model are not updated). If I submit the form again, it works. If I make a redirect just after the container redirection it works again (this is the trick I have implemented actually).
