Insert trying to insert values in the wrong order ------------------------------------------------- Key: HHH-4866 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4866 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1 Environment: Using Hibernate 3.3.1 in JBoss 5.0.0, connecting to a MySQL 5.0 database Reporter: Neil Stickels It appears for all of my inserts where I have multiple parameters of the same type, it will mix up the order. I am pretty new to Hibernate, so possibly I have something wrong. Here are what I think are the relevant files: StoreBrand.hbm.xml: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated Jan 10, 2010 12:38:41 AM by Hibernate Tools 3.2.4.GA --> <hibernate-mapping> <class name="com.shopperapp.dao.StoreBrand" table="STORE_BRANDS" catalog="shopper_app"> <composite-id name="id" class="com.shopperapp.dao.StoreBrandId"> <key-property name="storeId" type="int"> <column name="STORE_ID" /> </key-property> <key-property name="brandId" type="int"> <column name="BRAND_ID" /> </key-property> </composite-id> <many-to-one name="brand" class="com.shopperapp.dao.Brand" update="false" insert="false" fetch="select"> <column name="BRAND_ID" not-null="true" /> </many-to-one> <many-to-one name="store" class="com.shopperapp.dao.Store" update="false" insert="false" fetch="select"> <column name="STORE_ID" not-null="true" /> </many-to-one> </class> </hibernate-mapping> Bean calling the persistence code: StoreBrand sb = new StoreBrand(sbid, brand, store); StoreBrandHome sbHome = new StoreBrandHome(); sbHome.persist(sb); StoreBrandHome which does the persistence: public void persist(StoreBrand transientInstance) { log.debug("persisting StoreBrand instance"); try { sessionFactory.getCurrentSession().beginTransaction(); System.out.println("trying to persist store_id "+transientInstance.getStore().getId()+" and brand_id "+transientInstance.getBrand().getId()); sessionFactory.getCurrentSession().persist(transientInstance); sessionFactory.getCurrentSession().getTransaction().commit(); log.debug("persist successful"); } catch (RuntimeException re) { log.error("persist failed", re); throw re; } } As you can see, I have a debug statement before the insert showing the store_id and the brand_id that I am trying to persist.
