Hi, I've seen the error you describe before. It happened to me when a file- submitting ajax call fails when using a Content-Security-Policy. The problem is that an error is returned to the browser (in my case Chrome), which renders an error page inside the iframe used to submit files via ajax. This error page is not from the same origin as your application (localhost:9080), therefore access is blocked for wicket-ajax. It took me a while to figure this out and I suspect something similar is happening to you.
