Hi;
After using WebResponse to export excel then clicking a Link gives Page expired error.
Any suggestions ?
Thanks.
A:
Make sure that your classes that don't extend wicket components use implements Serializable, otherwise you will often see a Page Expired error.
If this doesn't help, copy and paste the error logs so we can see the exception being thrown.

Page map? Isn't that a single instance? What are you trying to achieve?

A:
The session expired page usually appears when your pages are not bookmarkable and you make a request for a page to the server but the server has a different version of the page that you have requested. It shouldn't have anything to do with the session time out which is defined in the web.xml file.
As a good practice, your pages should have a constructor with PageParameters. Also be careful with the popup pages because they usually generate these kind of errors when they are not using PageParameters.
