1 - N Mapping with Delete of N

Question

We are getting the n vector from the 1 object using indirection and attempting to remove one object from the vector.
Then, when performing a deepMergeClone on the 1 object, the appropriate delete statement is not being generated against the db???
Is this not the way it is supposed to work?

Answer 1

I have tried a simple test case in both 9.0.3 and 10.0.3 TopLink to try to reproduce what you are describing with no luck. The following code uses the employee domain example and uses indirection (ValueHolder) in both the 1:M and 1:1 back reference with PhoneNumber.
// Find Employee
     Employee employee = (Employee) session.readObject(Employee.class, exp);
// Create copy through serialization
Employee empCopy = copyEmployee(employee);
// Remove the first phone number from the copy
PhoneNumber phone = (PhoneNumber) empCopy.getPhoneNumbers().get(0);
empCopy.removePhoneNumber(phone);
UnitOfWork uow = session.acquireUnitOfWork();
uow.deepMergeClone(empCopy);
uow.commit();
One thing that came to mind as I was writing this. The removal of the PhoneNumber from the 1:M collection only results in a delete because the 1:M mapping is configured as privately owned.
If it was not privately-owned I would need to call uow.deleteObject(phone) as well.
