Hibernate, search by primary key returns all from table
===

I have this issue with Hibernate that when i try to retrieve unique result using criteria hibernate returns all the content from the table. 

            Session session = HibernateUtil.beginTransaction();
    		Customer c = new Customer();
    		c.setCustId(custId);
    		Example ex = Example.create(c);
    		Criteria criteria = HibernateUtil.getSession().createCriteria(Customer.class);
    		criteria.add(ex);
    		
    		Customer customer = (Customer)criteria.uniqueResult();
    		
    		
    		HibernateUtil.commitTransaction();
    		HibernateUtil.closeSession();


However querying the table with:

    Customer customer = (Customer)session.createSQLQuery("select * from customer_ where custid = :id")
    				.addEntity(Customer.class).setInteger("id",	custId).uniqueResult();


returns correct entry.
"custId" is the table's primary key. And the Customer class contains 2 @OneToMany mappings.
Do I need to add something to the criteria example above??

Thanks in advance.
