[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4015) one-to-one: foreign key: save Problem

one-to-one: foreign key: save Problem ------------------------------------- Key: HHH-4015 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4015 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.2.6 Reporter: Sandeep Vaid Priority: Critical I have one-to-one relationship between class A and class B <class name="A" table="TEMPA" > <id name="aaId" type="string" column="AID" length="10"> <generator class="assigned"></generator> </id> <one-to-one name="b" class="B" constrained="true" outer-join="false" cascade="save-update" /> </class> <class name="B" table="TEMPB" lazy="true"> <id name="baId" type="string" column="BID" length="10"> <generator class="foreign"> <param name="property">a</param> </generator> </id> <one-to-one name="a" class="A" /> </class> Problem 1: When i try to save A, it fires : insert into HBLEARN1.TEMPB (BID) values ('1') and throws error : The insert or update value of the FOREIGN KEY "TEMPB.CC1246876555824" is not equal to any value of the parent key of the parent table. SQLSTATE=23503 Why it is first trying to save 'B' instead of 'A' first ? Problem 2: With this mapping, if i set <property name="hibernate.hbm2ddl.auto">create</property> in hibernate.cfg.xml, It generates TEMPA whose aaId is the foreign key referencing TEMPB. This is also incorrect..
