I am trying out a simple one-many relationship using XDoclet :

The parent's XML :

and the class code :

The child's XML :

and the class code :

I am trying to add the child to the parent :

This causes the below failure :

This error does not happen if I follow the route of
- save parent and commit
- save child and commit
- add child to parent and commit

Anything I am doing wrong ?
