Private-owned deletes and batch writing test case

Question

Has someone dealt with the following scenario ?
I have an order containing order items a a private owned one-to-many relation ship.
When i delete many order lines toplink generates the delete commands for order items and orders. When using batch writing the delete commands are generated in a way that the batch writing is useless (each delete command is generated on its own batch command as the following:

If the test case does not define a private owned relation and all the deletes are done in the toplink application (first order items and the orders then the bach writing contains all the deletes.
Any hint to have batch writing and private-owned deletes behaving on the same batch chunk on Toplink 10.1.3.3 ?

Ok ill try to make a incompete code with the example of the problem in comments.
class studenttest;
//this is the messed up part all the way at the bottom of the class
            case 6:
                ts.write(NodeList);
                break;\\\\\\\\\\\\\\
public class TStream{
private StudentNodeList NodeList = new StudentNodeList();
//calls this method
//had it as public void write (StudentNodeList NodeList)
    public void write(Student NodeList)
        try
            output = new PrintWriter("database.txt");
            for(int i = 0; i < 5; i++)
// had it as output.print(NodeList.equals(LastName) + "\t");
                output.print(NodeList.getFirstname() + "\t");
                output.print(NodeList.getLastname() + "\t");
                output.print(NodeList.getID() + "\t");
                output.print(NodeList.getyear() + "\t"); 
                output.print(NodeList.getgpa() + "\t");   
                output.println();
          }
