I've partially solved the problem: it was being caused by an anonymous inner class in the page (CheckboxClickManager) that wasn't serializable. However making it serializable led to a different problem: now the user does not receive errors anymore, but the page he finally receives sometimes takes into account only a subset of the clicks. In other words, say the users clicks rows 1,2,3,4,5,6,7, then he waits for the server to finish processing all the clicks, and finally he receives a page where only rows 1 to 5 are checked (for example, maybe it's 1 to 3 or something). However I suspect this new problem is caused by hibernate not being able to lock database pages within 1 minute, though I'm not sure. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
