[Hibernate-JIRA] Commented: (HHH-1296) Non lazy loaded List updates done in wrong order, cause exception

by Uwe Schaefer (JIRA)

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1296?page=c... ] Uwe Schaefer commented on HHH-1296: ----------------------------------- About "getting this too when I remove() an entry from a List with an @IndexColumn. ": We´re facing the same serious trouble here. Is it true that using JoinTables to reflect ordered Lists is absolutely not working when using more than 2 references ? Is there any way to remove uniqueness from the inverseJoinColumn ? Using something like: @JoinTable( name = "rel_a_b", joinColumns = { @JoinColumn(name = "a_uid") }, inverseJoinColumns = { @JoinColumn(name = "b_uid", unique = false) } ) does not work, but would provide a workaround.

[Hibernate-JIRA] Commented: (HHH-1) Optimize Hibernate for the bulk insertion of related entities

by Martin Ross (JIRA)

An optimization can be applied in this scenario to group inserts / updates by entity class, or table. This will enable the hibernate engine to utilize batching if available, drastically improving performance over a network. -- 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

[Hibernate-JIRA] Created: (HHH-2337) Setting session-specific event listeners

by Wouter Lievens (JIRA)

Setting session-specific event listeners ---------------------------------------- Key: HHH-2337 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2337 Project: Hibernate3 Type: Improvement Components: core Environment: Hibernate 3.2.0, MySQL 5 Reporter: Wouter Lievens Priority: Minor Event listeners can be assigned programmatically to the Configuration object, but not to the Session or SessionFactory object. I want to be able to assign a new event listener, with different state, each time I create a new Hibernate session (or Factory). There is a workaround: you can cast the session factory to SessionFactoryImpl and use getEventListeners on that class, but since this is a "hack" it's unwise to leave it at that. The SessionFactory interface could be extended with the method getEventListeners, allowing to modify the EventListeners at that point, but maybe this issue goes deeper than just that. -- 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
