If with this changed mapping the same child object is added to the OneToOne and at the same time to the OneToMany association there in theory a "Chicken or the Egg" problem could arrise. In reality a test showed me, that hibernate in that situation executes two insert statements an an additional update statement to avoid that problem.<br> But in our test case there is no @joincolumn and additionally we never add the same child object to the OneToOne and to the OneToMany association.<br> In our application with thousands of entities we have a lot of constraint violations if we switch on order_inserts. With hibernate 3 this problem does'nt exist.<br> What can we do?</p> </td>
