Something like this will do the trick:
class PickyHttpSessionStore extends HttpSessionStore {
public PickyHttpSessionStore(Application application) {
super(application);
}
@Override
public void setAttribute(Request request, String name, Object value) {
try {
ObjectOutputStream stream = new ObjectOutputStream(new
ByteArrayOutputStream());
stream.writeObject(value);
stream.close();
} catch (IOException exception) {
throw new RuntimeException("Unable to serialize
value", exception);
}
super.setAttribute(request, name, value);
}
}
That said, this will only show error log entries, because of the catch
in RequestCycle:
try
{
getSession().requestDetached();
}
catch (RuntimeException re)
{
log.error("there was an error detaching the
request from the
session " + session +
".", re);
}
I would like to see an error page instead, errors of this kind end up
showing themselves as obscure page expiration issues that are hard to
trace if you don't know where to look.
