ViewExpiredException - Firefox only <p>Environment: JBoss 5.1, RichFaces 3.3.3 Final, Facelets 1.1.15.B1, Seam 2.2.0</p> <p>I am getting an unexpected ViewExpiredException with the following steps:</p> <ol> <li>Login</li> <li>Use app normally, then log-out (seam Identity.logout) which navigates back to login page</li> <li>Login again, navigate to page and select any postback action - showing modal panels, navigating to new sub-dialogues etc</li> </ol> <p>The thing is this - it only happens in a particular dialogue and only when using Firefox (Chrome &amp; IE are OK). I can happily use other dialogues but once I get into this particular dialogue it goes belly up. I've trawled the forums looking for solutions and have tried a number of recommended things such as a custom ViewHandler to cope with the session expiring whilst the browser is sat on the login page but idle (this works fine - trying to extend it to pages other than login gives an " No Converter was created" exception ) and a filter to prevent caching (as described in this forum) but nothing seems to stop this happening. I've set the facelets context parameter BUILD_BEFORE_RESTORE which again didn't help</p> <p>Anyone had a similar experience?</p> <p>The dialogue in question is quite complex in structure and is built from several includes, decorates etc so is nigh on impossible to list unfortunately but then I'm not sure it would help anyway.</p> <p>Any help would be very much appreciated</p> <p>Ian</p>
