[hibernate-issues] [Hibernate-JIRA] Created: (HHH-2449) Lazy loading for one-to-one asociations

Lazy loading for one-to-one asociations --------------------------------------- Key: HHH-2449 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2449 Project: Hibernate3 Type: New Feature Components: core Versions: 3.2.2 Environment: Hibernate 3.2.2 Reporter: jose After read "Some explanations on lazy loading" and my tests I found a lossing feature in Hibernate (3.2.2). one-to-one with lazy="proxy"_____________________________________________ Hibernate ALWAYS launch selects to know if one-to-one is null or can be proxied. one-to-one with lazy="no-proxy"__________________________________________ Instrumentation allows to hibernate modify the getter to allows lazy loading on demand: * but allways initialize ALL no-proxy relations (with first getter call) -> must initialize ONLY the requested property * never auto-initialize FETCH joins, ALWAYS doit on demand (if opened session) -> must auto-initialize ONLY the FETCHED property note: Can submit a fix for this? How? NEW FEATURE: one-to-one with lazy="proxy" without multiple SELECTS______ If Hibernate adds join, for all one-to-one relations, to get the foreign-key of other tables, can check it to create a proxy or null. note: that hibernate adds joins for hierarchy, why not for one-to-one relations? This solution avoids: * 'multiple subselects' after first select * 'instrumentation' of bytecode -- 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
