I can tell you that Struts doesn't cache your data anywhere for you. You 
may be storing a reference in the session or some other web-tier scope, 
holding it in a static field or otherwise keeping a stale reference 
somewhere. Or you may be seeing client-side page caching or even 
mis-configured caching at the Hibernate or database level.

You'll need to trace through your data access paths to determine at what 
point you're picking up the stale reference, and then figure out where 
that's coming from.
