Здравей, The error says that the component is not in the page anymore for any reason. Do you change the component tree somehow ? It could be that the slow operation changes the component tree while a second action is queued to be executed. Once the first operation finishes Wicket will allow the second to proceed and it will face this problem.
Wicket synchronizes the access to a Page instance so only one thread (i.e. one http request) can work with a Page instance at a time. If you fire two consecutive requests to the page then the first that hits the server is processed first and the second waits on the lock (see PageAccessSynchronizer).
