em.refresh() throws an error at me

[kh2ouija]

I have a domain model like this: Company -* Department -* Employee

On a Company's page I list all Departments with their Employees.
When I delete an Employee, the page has to be updated so I do this in the backing bean:

em.refresh(company);
departments = company.getDepartments();

When I refresh the company after deleting an employee I get this:

javax.ejb.EJBTransactionRolledbackException: javax.persistence.EntityNotFoundException: org.hibernate.UnresolvableObjectException: No row with the given identifier exists: [com.example.Employee#231]

Any idea why, or how to avoid this? Or maybe a different way of refreshing my view? Thanks.

Anyway, I think I know what the problem is, I just don't know how to fix it. I believe it's because I'm reading the Company in one bean, deleting the Employee in another (therefore withing a different PersistenceContext) and then refreshing it in the first bean again, so the PersistenceContexts aren't "in sync" anymore...

Just ignore the previous post; it happens even when deleting within the same PersistenceContext.
