Hello,
I'm struggling a bit with the concept of alias in Hibernate.
My situation is the following:
Order

@OneToMany(cascade=CascadeType.ALL,mappedBy="m_order")
private Set<OrderDetail> m_details;

OrderDetail

    @ManyToOne(cascade=CascadeType.ALL)
    @JoinColumn(name="product_id")
    private Product m_product;
    @ManyToOne(cascade=CascadeType.ALL)
    @JoinColumn(name="order_id")
    private Order m_order;

DAO

c.createAlias("m_details", "detail").createCriteria("detail.m_product").add(Expression.idEq(productId));

So I want to search every order that contains a product.
However, with this query it keeps returning 0 orders and I don't really see what I'm doing wrong.
Thanks!
