Hi, Wicket automatically uses IFrame (and since some time uses HTML5 FormData) when the request is Ajax. I guess your problem is related to this requirement: https://github.com/apache/wicket/blob/69b2e4c84eb097f55f7b02dfb17c6be057de2f6f/wicket-extensions/src/main/java/org/apache/wicket/extensions/ajax/markup/html/modal/ModalWindow.java#L118-L120 You need to wrap the modal window is inside a form.
