[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2299) dynamic-map entity mode mappings with relationships rise lazy initialization during performing query

dynamic-map entity mode mappings with relationships rise lazy initialization during performing query

--------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-2299 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2299 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.1 Reporter: Boleslaw Dawidowicz Attachments: hbTestCase.zip, hibernate-issue.tar.gz (copied from http://jira.jboss.com/jira/browse/HIBERNATE-51) (attached IntelliJ project with test case that reproduce this issue) If I create bidirectional relationship between two dynamic-map entities, commit a transaction and start new session, performing a query to obtain an entity raise LazyInitializationException. (full intellij project attached) code and mappings: public void testSF() throws Exception { sf.openSession(); Session es = sf.getCurrentSession(); Transaction tx = es.beginTransaction(); Map lolo = new HashMap(); lolo.put("userName", "lolo"); es.save("PortalUser", lolo); Map dummy = new HashMap(); dummy.put("name", "dummy"); es.save("PortalRole", dummy); Set roles = new HashSet(); roles.add(dummy); lolo.put("roles",roles); Map props = new HashMap(); props.put("theme", "pp"); props.put("signature", "alalala"); lolo.put("dynamic", props); es.save("PortalUser", lolo); tx.commit(); sf.openSession(); es = sf.getCurrentSession(); tx = es.beginTransaction(); Query query = es.createQuery("from PortalUser where userName=:userName"); query.setParameter("userName", "lolo"); //LazyInitializationException on this LINE!!! lolo = (Map)query.uniqueResult(); assertNotNull(lolo.get("roles")); assertNotNull(lolo.get("dynamic")); tx.commit(); } <hibernate-mapping> <class

com.intellij.rt.execution.application.AppMain.main(AppMain.java:90) also note that commenting out this 3 lines makes it work: Set roles = new HashSet(); roles.add(dummy); lolo.put("roles",roles); So I guess it's about resolving roles relationship during obtaing a user object
