Thanks, that really clears it up. At first glance, synchronizing pages on the session seems a little overly restrictive (Scott's issue being a case in point), but of course *not* synchronizing on the session is an infamous source of frustrating bugs, even in frameworks with much simpler state handling than Wicket.
Very cool, I would much rather have to intentionally enable multithreaded operations on a case-by-case basis than have to constantly worry about subtle multithreading issues. -Ryan On Feb 14, 2007, at 1:54 AM, Eelco Hillenius wrote: > On 2/14/07, Ryan Holmes <[EMAIL PROTECTED]> wrote: >> It sounds like Scott just wants to allow the user to "cancel" the >> slow-loading page by navigating to another page. > > Or at least don't show a blank page that'll provoke the user to hit > refresh ten times in a row. > >> If his database >> request happened in a LoadableDetachableModel rather than a page >> constructor, would that allow a new page to be rendered while the old >> one is still trying to load data? > > No, that doesn't make a difference.
