Subject Re: ViewExpiredException, but session hasn't timed out
Date Thu, 10 Apr 2014 12:05:52 GMT
It's necessary to have a slow internet connection to reproduce this, so I
can't test locally. While the page is loading the user hits a command
button. As the page is still loading, I guess the view state is not created
yet, so viewHandler.restoreView(facesContext, viewId) returns null.

Thanks for the suggestion. I'll give it try, but according to the component
documentation, using it for this case feels more like a workaround than a
solution, so I'd like to see if there are more options.
