Hi,
here I am again. I have a problem with references. Marshalling is OK, but
while unmarshalling, I get exception: ValidationException: unable to resolve
reference: 2.
I can't figure out what is the problem here.
This is my object model.
public abstract calss Entity{
private Integer id;
//other
//getters and setters
}
public class ArithmeticTree{
private ConnectorNode root;
private Set<AbsractInputNode> inputNodes;
//other
//getters and setters
}
public abstract class AbstractTreeNode extends Entity{
private AbstractTreeNode parent;
private ArrayList<AbstractTreeNode> children;
private AbstractInputNode inputNode;
//other
//getters and setters
}
public class ConnectorNode extends AbstractTreeNode{
//some members
//getters and setters
}
public class MemberNode extends AbstractTreeNode{
//some members
//getters and setters
}
public abstract class AbstractInputNode extends Entity{
//some members
//getters and setters
}
public class InputNode extends AbstractInputNode{
//some members
//getters and setters
}
