failure to lazy load a manyToOne and oneToMany mapped entity ------------------------------------------------------------ Key: HHH-3798 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3798 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1, 3.5 Environment: hibernate annotations test case, maven profile hsqldb, svn rev 16079 hibernate-core 3.3.1.GA, JBoss 4.2.3, SQLServer 2000 Reporter: Ronald Kurz Attachments: test-case.tar.gz Following situtation: an entity Data has Revision entities (oneToMany). Each Revision entity belongs to a Data entity. The Data entity has one manyToOne mapping to the current Revision. The mappings from Data to Revision are all lazy. When loading a Data entity, which has two Revisions, the Revision entity which is also mapped as manyToOne (the current Revision for that Data entity), does not get loaded. It will be an uninitialized proxy, which is also resistent to Hibernate.initialize(<Data>.revision). The same proxy is also in the oneToMany mapped list. @Entity public class Data { @Id @GeneratedValue public int id; @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "revisionId") public Revision revision; @OneToMany(mappedBy = "data") public List<Revision> revisions = new ArrayList<Revision>(); } @Entity public class Revision { @Id @GeneratedValue public int id; @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "dataId", nullable = false, updatable = false) public Data data; public Integer number; } The test case is written for the hibernate-annotations project (simply because I never wrote a mapping using xml) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
