[ http://jira.jboss.com/jira/browse/EJBTHREE-425?page=comments#action_12372898 ] Carsten Christensen commented on EJBTHREE-425: ---------------------------------------------- Hi, i still see this error, and none of the workarounds seems to work. My Entity is in a inherritance heraki, where i have @Entity @Inheritance(strategy=InheritanceType.JOINED) public abstract class Element implements Serializable { @Id @GeneratedValue @Column(name = "elementId", unique = true, nullable = false) @NotNull private int elementId; @ManyToOne(optional=true) @JoinColumn(name="pageId", nullable=false) private Page page; ..... } @Entity public class ExtElement extends Element { //, cascade=CascadeType.ALL @OneToMany(fetch = FetchType.EAGER, mappedBy="explainText") @MapKey(name="languageId") private Map<Integer,ExtElementLanguage> extElementLanguages; .... } when i do em.remove(em.merge(element)); i get the error: 09:18:56,332 FATAL [application] javax.ejb.EJBTransactionRolledbackException: deleted entity passed to persist: [my.package.Element#<null>] javax.faces.el.EvaluationException: javax.ejb.EJBTransactionRolledbackException: deleted entity passed to persist: [my.package.Element#<null>] at javax.faces.component.MethodBindingMethodExpressionAdapter.invoke(MethodBindingMethodExpressionAdapter.java:91) ...... This is badly influencing customers, do you have any solution? have tried to split the line to em.merge(element); em.remove.element() toss in flush and clear() etc -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
