You are most likely "losing" the data because you are not linking the
child to the parent. By setting up the child to automatically be added
and the parent link filled, you should avoid this.
You can then set up some code in your child's beforeSave() method to
check for non-empty values, and if none are found, issue a
self.cancel() to remove the empty record.
