Thanks for the answer, Ernesto. A message has quite complex layout, it would be a lot of work to redo it in json. And I lose all benefits of wicket tester... Yes, that's that I mean by fighting the wicket, do everything manually, not using the wicket... Is it only solution? It worries me because I have to rewrite quite a few such pages - if a page has a lot of data, I cannot use wicket's AJAX abilities.
