Hi There is no magical solutions to you problem. You should check which value has javax.faces.ViewState request parameter in the POST request that causes the ViewExpiredException. Put a filter or a PhaseListener that logs that value when there is an incoming request to that view. The key point is to know if the view state token is there or not and if it has been altered somehow between the time the page is renderer and the time the button is clicked and the POST is sended. You need to log the token saved on the page too, to know the original value.
One option I can imagine is that the value in the ViewState token is sent partially. The server received the trimmed token, it doesn't match because it is broken and it throws correctly the ViewExpiredException. But sounds unlikely, we need more evidence about what's going on. What I can say is the code in MyFaces Core is ok in that part and specifically the state management code has been tested exhaustively. It is quite unlikely to find a bug in that part. regards, Leonardo Uribe 2013/9/27 Zmirc <zmircmir...@gmail.com> > Hi again! > > Any ideas / fixes for this bug? > It's still there and is completely random. > Moreover, I can't reproduce it. > > Please don't ignore it, because it's a real pain in the ... > It's screwing up the whole project, because some users get this bug > randomly, whenever they execute a post (command button). > > Thank you so so much in advance. > > > On 9/25/2013 12:17 PM, Zmirc wrote: > >> Hi! >> Some users (few) of the app I work on experience a very strange error, >> which I can't yet reproduce. >> Moreover, it appears in less than 10~ of executions. >> >> Error: No saved view state could be found for the view identifier: >> /mypage.xhtml >> >> Application server: Apache Tomee 1.5.2 stable / 1.6.0-2013.09.20 dev (It >> happens on both).
