Well, I have now managed to get both the textarea updated while my background thread is running, and the dropdownchoice updated when the thread is finished. For that I use an AbstractAjaxTimerBehavior that I add to the textarea component (I guess I could also add it to my Page). Then, on the onTimer() method I add the textarea and/or the dropdownchoice to the target. So far, so good. The only problem now is that the timer is running all the time, even when I do not needed (i.e. even when the background thread is not running). I would like to start the timer when I launch the background thread and stop it when the thread is finished. I saw here (https://issues.apache.org/jira/browse/WICKET-1525) that there are plans to have a resettable timer. I tried to use the AbstractAjaxRestartableTimerBehavior class provided there, but I have encountered a problem. I create an AbstractAjaxRestartableTimerBehavior timer and add it to my Page. In the onTimer() method I check whether I have to update the textarea and the dropdownchoice and, if so, I add them to the target. If I find out that the background thread has finished, I also stop the timer (i.e. I stop the timer inside the onTimer() method). Everything works fine until I stop the timer. The onTimer() method finishes ok, but then I get an "Access Denied" message on the browser and the following warning: WARN - RequestListenerInterface - behavior not enabled; ignore call. Behavior test.web.gui.Index$1@17574b9 at component [Page class = test.web.gui.Index, id = 1, render count = 2] More details: My Page consists of a textarea, a timer and a form. The form contains the dropdownchoice. I have tried adding the timer to the textarea, but get the same error (but for the textarea component). I have tried submitting the form via Ajax and normally. Same error. Hope you know what the problem is and can help me.
