We're getting a lot of StalePageException, immediately followed by "An error occurred while checking whether a page is stateless. Assuming it is stateful." on stateful pages and especially when crawled by Google bot.
Any idea why this is happening? @timestamp 2013-09-24T01:42:47-04:00 caller Caller+0 at org.apache.wicket.request.RequestHandlerStack.detach(RequestHandlerStack.java:184) Caller+1 at org.apache.wicket.request.cycle.RequestCycle.onDetach(RequestCycle.java:636) Caller+2 at org.apache.wicket.request.cycle.RequestCycle.detach(RequestCycle.java:589) Caller+3 at org.apache.wicket.request.cycle.RequestCycle.processRequestAndDetach(RequestCycle.java:293) Caller+4 at org.apache.wicket.protocol.http.WicketFilter.processRequestCycle(WicketFilter.java:259) level ERROR logger org.apache.wicket.request.RequestHandlerStack message Error detaching RequestHandler req.queryString 0-1.IBehaviorListener.1-productStatusPanel-addToCartRegion-1-productCartComposeForm-quantityProductPanel-quantity req.remoteHost 127.0.0.1 req.requestURI /tuneeca_prd_commerce/app/product/gamis-je-t-aime-champs-elyses req.requestURL http://localhost:8201/tuneeca_prd_commerce/app/product/gamis-je-t-aime-champs-elyses req.sessionId 369EExxxx req.userAgent Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) req.xForwardedFor 66.249.66.172 thread http-nio-8201-exec-17 throwable org.apache.wicket.core.request.mapper.StalePageException: null followed by : @timestamp 2013-09-24T01:42:47-04:00 caller Caller+0 at org.apache.wicket.page.RequestAdapter.commitRequest(RequestAdapter.java:170) Caller+1 at org.apache.wicket.page.AbstractPageManager.commitRequest(AbstractPageManager.java:98) Caller+2 at org.apache.wicket.page.PageManagerDecorator.commitRequest(PageManagerDecorator.java:73) Caller+3 at org.apache.wicket.page.PageAccessSynchronizer$2.commitRequest(PageAccessSynchronizer.java:281) Caller+4 at org.apache.wicket.Application$2.onDetach(Application.java:1628) level WARN logger org.apache.wicket.page.RequestAdapter message An error occurred while checking whether a page is stateless.

id.co.bippo.product.web.pub.ProductShowPage.getAddToCartRegion() is simply calling a method on a Component (saved in field) that's supposed to be created during the ProductShowPage's constructor. So it seems either the constructor wasn't properly called/finished or something else happened, so the component was null. * our site's usage pattern is: - for frontend, a lot of concurrent users (50-100s), all accessing stateful pages, and usually they open several tabs - for the backend, several concurrent users (15s), all accessing stateful pages, and each open 10-20 tabs * configuration is deployment. However wicket-devutils.jar is on the WEB-INF/lib (because the same dependency is required during development), does this affect? * Tomcat 7.0 on Oracle JDK 7 on Ubuntu 12.10 64-bit * using Tomcat's PersistentManager FileStore for session I found a couple of threads related to StalePageException in Wicket 1.5 : 1. http://apache-wicket.1842946.n4.nabble.com/StalePageException-handling-issue-td4579247.html 2. http://apache-wicket.1842946.n4.nabble.com/Getting-more-stale-page-exception-in-wicket-1-5-6-td4649492.html But these are for Wicket 1.5 so I'm not sure if it applies. Any suggestion would be appreciated. Thank you.
