I have an entity DepartmentEmployee and lazy property department there:

Code:

@ManyToOne (fetch = FetchType.LAZY)
Department department;

For geting department list I use Criteria:

Code:

Criteria cr = session.createCriteria(DepartmentEmployee.class);
cr.setFetchMode("department", FetchMode.JOIN);
cr.add(Restrictions.eq("somekey", "somevalue"));
cr.setProjection(Property.forName("department") );
result = cr.list();

But Department object in this list still lazily initialized.
So why FetchMode.JOIN doesn't work?

Hi kostepanych

I will paste my mapping which works with my criteria queries using EAGER fetch strategies (queries very similar to your criteria query):

Code:

   @ManyToOne(fetch = FetchType.LAZY)
   @JoinColumn(name="CUSTOMER_ID", nullable=false)
   public customerAll getCustomerAll()
   {
      return customerAll;
   }

Hope this helps.

Regards, Adam Woźniak

I've found that FetchMode.JOIN doesn't work when I use cr.setProjection(Property.forName("department")). Without this projection it works good. So, does anybody know why?
