Hi all
I'm trying to create a Node class, where every Node has a pointer to a
parent Node (or null if there is none).
A simplified view of the Node-class looks like this:
@Entity
public class Node {
@Id protected long id;
@ManyToOne(fetch=LAZY)
protected Node parent;
protected String name;
protected String displayName;
// setters / getters..
}
And this was working correctly in TopLink (I think they just do infinite
recursion depth), but in OpenJPA i get something that looks like recursion
errors.
Is there a better way of doing this? I have implemented a hack just using
long parentId instead, but that kinda sucks when you are deleting and
updating nodes.
I know there is something called FetchGroups in OpenJPA, but i couldn't
really get them to work and I want to have entities that hopefully isn't
tied down to OpenJPA.
