Events of this type are either sent to an object that implements {@link ScriptSessionBindingListener} when it is bound or unbound from asession that has been configured in the deployment descriptor when any attribute is bound, unbound or replaced in a session.
The session binds the object by a call to ScriptSession.setAttribute
and unbinds the object by a call to ScriptSession.removeAttribute
.
