Hi,
I have solved the problem, overriding valueUnbound in my custom session and
updating the database
with my @SpringBeans works when the session is expiring. My problem was
that I was using data
from my session in the @Repository Dao impl class like this:
MyCustomSession.get() and that issued the "There is no application attached
to current thread ContainerBackgroundProcessor" exception.
Many thanks for the help.
Best regards
Daniela
