I want two one-to-one relations from TableA to TableB and from TableA and TableC, and the TableA is parent of TableB and TableC.
When I use SchemaExport to generate database schema from these xml files, the relationship is wrong, like following:
alter table TableB add constraint FK40D42F9928CEC8B7 foreign key (ID) references TableA;
alter table TableC add constraint FK256DA2AC28CEC8B7 foreign key (ID) references TableA;
alter table TableA add constraint FKEAF0462728CEC8B7 foreign key (ID) references TableC;
--the third line should not be generated!
when i write one-to-one mapping from tableA to tableC before tableA to tableB in ClassA.hbm.xml, the error is tableB.
