Hi, It seems to be caused by https://github.com/apache/wicket/commit/562d43ccdd7f305f8ca641817f4b63a07ee8b6a6 As the commit message says this container should be removed before the end of the request cycle, so it won't lead to such problem in the normal cases. But combined with the DebugBar it breaks... Please open a ticket. With a quickstart / test case would be perfect!
