Hi, 1. Firstly, I did take a look at all posts regarding this exception available on PEE like here<http://issues.apache.org/jira/sr/jira.issueviews:searchrequest-fullcontent/temp/SearchRequest.html?query=PageExpiredException&summary=true&description=true&body=true&tempMax=1000>and here<http://markmail.org/search/bookmarkable+page+and+PageExpiredException%20> 2. Secondly, Its not a Serialization issue as most conclude and that the exception occurs every time there is an ajax call happens with pages from apps are opened in 2 tabs 3. I do not implement any other algorithms and use the packaged SessionStore 4. Session is not invalidated and PageMaps are not quenched and the default PageMap = null is in place and pages are serialized and deserialized to diskstore 5. The URL looks like this at exception occurence http://localhost:8080/myApp/secure/jas/tom/?wicket:interface=:3:::: 6. Exception trace is as such org.apache.wicket.protocol.http.PageExpiredException: Cannot find the rendered page in session [pagemap=null,componentPath=2:xyzPanel:xyzForm:filter:viewButton,versionNumber=0]
