Hibernate's CascadeType causes compile errors

Hibernate version: Annotations 3.2

Hi,

I'm having compilation problems when trying to use Hibernate's CascadeType. I get these errors no matter which CascadeType I use as long as it is from org.hibernate.annotations.CascadeType.

Code:

import javax.persistence.ManyToMany;
import org.hibernate.annotations.CascadeType;

class Customer {
    private Order orders;

    @ManyToMany(cascade=CascadeType.LOCK)
    public Order getOrders() {
        return orders;
    }
}

I get the compilation error:
Type mismatch: cannot convert from CascadeType to CascadeType[]

if I change the cascade to:

Code:

@ManyToMany(cascade={CascadeType.LOCK})

I get the compilation error:
Type mismatch: cannot convert from CascadeType to CascadeType

Is this a bug or am I don't something wrong?

Are you sure this is ok?

public Order getOrders() {
return orders;
}

It should be something like "Set<Order> getOrders()"

actually, that was just some code that I typed for the post and it's not really like that in real-life. The important thing is the cascade. If I use the java persistence class (without the LOCK), then it works. It's really the Hibernate class which doesn't work

well @ManyToOne accepts javax.persistence.CascadeType not org.hibernate.annotations.CascadeType.

remember that javax.* are specifications and are not dependent to any implementation.

you must use @org.hibernate.annotations.Cascade annotation for using org.hibernate.annotations.CascadeType.

Ok, I used the @Cascade annotation and that worked, but this annotation isn't mentioned in the Hibernate Annotations reference at all. If this is what I have to use, then it should be documented.

well I don't know which version of Hibernate Annotations you use, but it is documented in Hibernate Annotations 3.2 g.a.
