Hi! My colleague noticed some dodgy behavior, which I think could be a bug. Just asking here if it's known, befor I try to create a quickstart or PR.
* page is rendered * user interacts with a page causing ajax request (clicking checkbox) * the wicket PageAccessSynchronizer locks, renders and unlocks the page with that id * after that, custom request logger asks for the className of the current page * the PageProvider doesn't have it on hand, so has to ask for the page from DefaultMapperContext#getPageInstance * that in turn locks the page again -- without unlocking it * so subsequent interaction with the same component blows up after a minute of not being able to get the lock for the page Wicket 8.5.0 The stack trace org.apache.wicket.page.CouldNotLockPageException: Could not lock page 86. Attempt lasted 1 minute at org.apache.wicket.page.PageAccessSynchronizer.lockPage(PageAccessSynchronizer.java:168) at
