Re: Threading problem
Thank you very much for this explanation, Igor. Very much appreciated. - Kaspar On 16.10.2008, at 18:14, Igor Vaynberg wrote: requests from a single session are serialized. but what if your page is stateless and you click the two links fast? each click spins off a request that now needs a session and because they run concurrently two sessions are created because this is the first request that needs a session. try doing this in your page's constructor: Session.get().bind(); this will force wicket to create a http session when the page renders and will avoid this kind of problem. -igor On Thu, Oct 16, 2008 at 9:02 AM, Kaspar Fischer [EMAIL PROTECTED]wrote: I run into a concurrency issue: My pages load fine when I visit them slowly, one after the other with a pause between clicks.
