    Two tables A and B where B is parent table and the relation between A and B is unidirectional many-to-one. mapping for A: <hibernate-mapping package="parms"> <class name="A" table="A" lazy="true" batch-size="20" select-before-update='true' > <id name="id" column="ID"> <generator class="increment"/> </id> <many-to-one name="b" column="Ba_ID" class="B" not-found="ignore" cascade="none" lazy="false" not-null="false" unique="false" /> <property name="place" column="PLACE"/> </class> mapping for B: <class name="B" table="B" lazy="true" batch-size="10" select-before-update="true"> <cache usage="read-write"/> <id name="id" column="B_ID" > <generator class="assigned"/> </id> <property name="programId" column="GROUP_ID" unique="true"/> </class> Also some of rows of table A have null values for column Ba_ID. Now retrieval of these rows which have null values for column Ba_ID works fine. And it retrieves a null relationship between the tables for these rows. Now when I try to update column PLACE. It tries to update column Ba_ID also and there it throws a TransientOBjectException. But nothing is being changed for that column. Also cascade is set to "none". Transaction scope code A a=_form.getA(id); a.setPlace("place"); sess.saveOrUpdate(a); tx.commit(); sess.close(); And the last SQL statement being tried to be executed is: UPDATE A set ......(all columns )..... where ID =? And the exception thrown is: [ERROR] AbstractFlushingEventListener - -Could not synchronize database state with session <org.hibernate.TransientObjectException: B> at org.hibernate.engine.ForeignKeys.getEntityIdentifierIfNotUnsaved(ForeignKeys.java:219)
