Kevin,
I think this is a bug, I had the same problem.
What is happening is that when the page is being enhanced (subclass created)
the reference to the injected object (a spring object in your case) is passed
through the constructor. Now since the page is pooled, the next time a request
is made the requested is serviced with this cached page along with the original
(stale) injected object.
I had to modify InjectObjectWorker class so that the reference is not passed
through the constructor but rather as a getter object that looks up spring's
application context every time. Take a look at this class's inject object
method.
Regards,
Amir
