Plz help me in this,

when will be the valueBound() mtd called, that is after session.setAtribute() or else before session.setAttribute.
And will be the valueUnBound() mtd called, that is after session.removeAttribute() or else before session.removeAttribute().

When the session is invalidate, when is the valueUnBound() mtd will be called that is before the session is invalidated or else after the session is invalidate.

Please help me in this...
