Abstract relationship

[Charlie Wu]

I have an Abstract base class A, which subclass to B and C, also I have a class D that have a one to many relationship to class B and C, what i really want to do is let D to have one to many relationship to class A

public abstract class A {

    @ForeignCollectionField

    private Collection<D> d;

}

@DatabaseTable

public class B extends A {

}

@DatabaseTable

public class C extends A {

}

@DatabaseTable

public class D {

    @DatabaseField(foreign = true)

    private A a;

}

but with this setup I get an error about foreign field mismatch.  Is this possible to archive in ORMLite?
