sessionDestroyed() is not called on invalidate

[softjack]

Hi,
I just created a listener class for session handling.
When a session is created, my
sessionCreated(HttpSessionEvent se) method is called.
similarly when the session is destroyed after timeout sessionDestroyed (HttpSessionEvent se)method is called.

My problem is that when i try to invalidate the session manually by calling session.invalidate(), the sessionDestroyed (HttpSessionEvent se)method is not called.

Can somebody throw some light on it...Am i doing something wrong...please help!
