Hi, It sounds like you are using Ajax fallback links, and the javascript event handlers are not properly registered or firing. If that happens, the link is processed like a normal/non-ajax link.
When you inspect the Ajax response when the list is refreshed, do you see “Wicket.Ajax.ajax” javascript calls?

On one page, we have a list of elements. When we click on an "Add Button", an ajax panel is modified in the page to add a new element in the list. When the "submit button" (ajax) is clicked, the list is refreshed (added to the ajax target). But the puzzling thing, now, is that the Ajax buttons, in the list, do not have an ajax target when clicked (the optional is empty, and from what I've seen so far, the listener doesn't consider it has been called within an Ajax request). This only happens when the list has been refreshed, when it is populated initially, the button triggers properly an ajax listener. And this didn't happen with the same code on Wicket 7. Is that a known issue? How can I investigate further? Regards
