Incorrect documentation regarding XML manipulation in Hibernate reference manual (chapter 18.3). ------------------------------------------------------------------------------------------------ Key: HHH-1920 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1920 Project: Hibernate3 Issue Type: Bug Components: documentation Affects Versions: 3.1.3 Reporter: Ignat Zapolsky Assignee: Diego Pires Plentz Priority: Trivial Manual has following sample (chapter 18.3): Session session = factory.openSession(); Session dom4jSession = session.getSession(EntityMode.DOM4J); Transaction tx = session.beginTransaction(); List results = dom4jSession .createQuery("from Customer c left join fetch c.accounts where c.lastName like :lastName") .list(); for ( int i=0; i<results.size(); i++ ) { //add the customer data to the XML document Element customer = (Element) results.get(i); doc.add(customer); } Mentioned code simply changes root node of doc, but supposed to add child elements. Correct code shall look like: Session session = factory.openSession(); Session dom4jSession = session.getSession(EntityMode.DOM4J); Transaction tx = session.beginTransaction(); List results = dom4jSession .createQuery("from Customer c left join fetch c.accounts where c.lastName like :lastName") .list(); for ( int i=0; i<results.size(); i++ ) { //add the customer data to the XML document Element customer = (Element) results.get(i); doc.getRootEelemnt().add(customer); }
