Hi,
after clicking (not idling) in my application a while I get the following Exception. By
pressing back-button and continuing work, all is fine again for a while, until I get the
same Exception. I`m confused, bcause I have no Idea, how it can come to this, except that
my session-scoped SFSB times out, but that should not be the case, because I configured
the timeout with @CacheConfig to be more than the session timeout and as I said, i`m
clicking around and not idling.
