Hi, i have a problem with entity listeners using @PreUpdate to modify the data. There are two entity beans, the first contains a collection of the second entity bean => OneToMany-Mapping. Something like that: | @Entity | @Table(name = "TEST_FIRSTBEAN") | public class FirstBean implements Serializable { | | private static final long serialVersionUID = 8150999009636714523L; | | private Integer id; | private Integer state; | private Set<SecondBean> secondBeans = new HashSet<SecondBean>(0); | | public FirstBean() { | } | | @Id | @GeneratedValue(strategy = GenerationType.AUTO) | @Column(name = "ID", unique = true, nullable = false, precision = 22, scale = 0) | public Integer getId() { | return this.id; | } | | public void setId(Integer id) { | this.id = id; | } | | @Column(name = "STATE") | public Integer getState() { | return this.state; | } | | public void setState(Integer state) { | this.state = state; | } | | @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy = "firstBean") | public Set<SecondBean> getSecondBeans() { | return this.secondBeans; | } | | public void setSecondBeans(Set<SecondBean> bBeans) { | this.secondBeans = bBeans; | } | | } | and | @Entity | @Table(name = "TEST_SECONDBEAN") | public class SecondBean implements Serializable { | private static final long serialVersionUID = -5353954801248924436L; | | private Integer id; | private Integer state; | private FirstBean firstBean; | | public SecondBean() { | } | | @Id | @GeneratedValue(strategy = GenerationType.AUTO) | @Column(name = "ID", unique = true, nullable = false, precision = 22, scale = 0) | public Integer getId() { | return this.id; | } | | public void setId(Integer id) { | this.id = id; | } | | @Column(name = "STATE") | public Integer getState() { | return this.state; | } | | public void setState(Integer state) { | this.state = state; | } | | @ManyToOne(fetch = FetchType.EAGER) | @JoinColumn(name = "FIRSTBEAN_ID") | public FirstBean getFirstBean() { | return this.firstBean; | } | | public void setFirstBean(FirstBean firstBean) { | this.firstBean = firstBean; | } | | } | There is also a simple entity listener. In the PreUpdate-Method It will set the state of the second beans, if the state of the first bean was set. Something like this: | public class FirstBeanEntityListener { | private static final Logger LOGGER = Logger.getLogger(FirstBeanEntityListener.class); | | public FirstBeanEntityListener() { | super(); | } | | @PreUpdate | public void preUpdate(final FirstBean bean) throws NamingException { | LOGGER.info("* FirstBean '"+bean.getName()+"' entity listener: @preUpdate called"); | | if (bean != null && bean.getState() != null) { | LOGGER.info(" FirstBean '"+bean.getName()+"': state set"); | | for (SecondBean childBeans : bean.getSecondBeans()) { | LOGGER.info(" set state for second bean: " + childBeans.getName()); | childBeans.setState(new Integer(1)); | } | } | } | | } | The entity listener is bound to the entity bean using orm.xml: <?xml version="1.0" encoding="UTF-8"?> | <entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_1_0.xsd" version="1.0"> | <entity class="FirstBean"> | <entity-listeners> | <entity-listener class="FirstBeanEntityListener" /> | </entity-listeners> | </entity> | </entity-mappings> The problem is now: If i have one FirstBean with any number of second beans, and i set the state of the first bean on client side, merge it in a stateless session bean and look at the database after that, state of one SecondBean wasn't set, but all others are set. Assume a jUnit test like that: public class EntityBeanListenerTest { | | private TestServiceRemote testRemoteBean = null; | | @Before | public void setUp() throws NamingException, RemoteCheckedException { | //Perform lookup: | ... | this.testRemoteBean = (TestServiceRemote) ctx.lookup("TestService"); | } | | @After | public void tearDown() throws Exception { | this.testRemoteBean = null; | } | | private FirstBean createSampleFirstBean() { | final FirstBean firstBean; | final SecondBean secondBean1; | final SecondBean secondBean2; | final SecondBean secondBean3; | | //Init first bean | firstBean = new FirstBean(); | | //Init second beans | secondBean1 = new SecondBean(); | secondBean2 = new SecondBean(); | secondBean3 = new SecondBean(); | | //Add second beans to first bean | firstBean.getSecondBeans().add(secondBean1); | firstBean.getSecondBeans().add(secondBean2); | firstBean.getSecondBeans().add(secondBean3); | | secondBean1.setFirstBean(firstBean); | secondBean2.setFirstBean(firstBean); | secondBean3.setFirstBean(firstBean); | | return firstBean; | } | | @Test | public void testFirstBeanDeletion() throws RemoteCheckedException { | FirstBean firstBean; | | //Reset database, will only clean table data | this.testRemoteBean.resetDatabase(); | | //Create data | firstBean = this.createSampleFirstBean(); | | //Save data and retrieve persisted data | this.testRemoteBean.persistFirstBean(firstBean); | firstBean = this.testRemoteBean.getFirstBean(); | | firstBean.setState(new Integer(1)); | this.testRemoteBean.mergeFirstBean(firstBean); | firstBean = this.testRemoteBean.getFirstBean(); | | for (final SecondBean secondBean : firstBean.getSecondBeans()) { | //This will fail on one bean, which one is indeterministic | Assert.assertNotNull("Second beans have not been deleted", secondBean.getState()); | } | } | | } I though the listeners should set all states of second beans, but for one second bean, the state wasn't set. If i perform a flush after merging the data in the same transaction in the session bean, the jUnit test will pass. Can anyone explain, why this happens? Am i doing something wrong? Must i always perform a flush? I am using JBoss AS 4.2.2 GA. Thanks in advance, Markus View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4144737#...
