IoC Question

Question about Tapestry's IoC system.  Let's pretend I register a service
called EventTracker.java.  EventTracker has a private List field containing
a list of Events, a method to add those events, and a method to retrieve
those events.  Now let's say I have another class that @Inject's that
EventTracker service and records a bunch of events.

If I @Inject the EventTracker service into yet another class, can I read
those events that the previous class added?  Or will it be an empty slate?
Generally, my question is this: do services save their state in between
injections in different classes?
