Hibernate java list not updating radiocarbon dating equation

Document Person Ccs, updating it, and then setting the new collection and updating it again, but I still get the same error.
I am trying to change one or more of these collections in my code, but Hibernate is not calling the update query when I expect it.It does call the update query when I change one of the regular fields (like the document subject), but even then it does not persist any of the one-to-many changes within the database.What do I need to change in order to get it to work?And it does not give any error about Type Missmatch or similar. Doing so the correct values are in the database and in your entity without doing a "refresh". The database column is a simple "TIMESTAMP" without any further functionality.So the database hasn't any logic, all is done by the application in one place.
