Hi
I have found the bug. The problem was caused on a refactor, there was an
old code that skip state saving when view map is empty, but now since there
is a proxy for that implementing StateHolder, the map can be empty but it
holds the view scope key. Since with CDI the beans are stored internally,
the map keeps empty but the scope is not, and if the view scope key is lost
the bean is recreated every time. But the beans are still in session, and
with the session timeout bug the final result is @PreDestroy is not called.
Please try again with the latest code, it should work. And please lets us
know what happened, if it is working or not.
regards,
Leonardo Uribe
