[hibernate-users] Retrieving clean Entity from EntityManager

Good Afternoon, I am using Hibernate behing JPA and have the following problem. My application pulls an entity out using the find operation of the EntityManager, and then somewhere else in my application I want to pull the same Entity out again cleanly with the current database state rather than the dirty version but any time I try I get the same dirty data. I have tried to detach the dirty version and then fetch the Entity again but it is still same. I have also tried the CacheRetrieveMode.BYPASS hint on the fetch in case it is a caching problem. How can I fetch a clean instance of my Entity side by side with the dirty version? Thanks Chris
