I am getting the following error when I am trying to update some of my records.

I am doing the update like this


Contact myContact = session.load(Contact.class, new Integer(6));
myContact.setFirstName("new name");
session.update(myContact);
session.flush();
session.clear();

The session.update() is unnecessary. And you may have a problem with your mappings. Post your mappings for Contact and TaskItem, and maybe that will help someone to be able answer your question.
