[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3876) collection [] was not processed by flush() triggering for unknown reasons

collection [] was not processed by flush() triggering for unknown reasons ------------------------------------------------------------------------- Key: HHH-3876 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3876 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5 Reporter: Mark Derricutt We've started to notice the following exceptions being triggered from Hibernate 3.5.0-SNAPSHOT (built locally), but only under certain circumstances (editing a specific user, whilst being logged into the application as a specific user). After stepping through both our application and hibernate through the whole update/commit process being run, I can't find anything that would be causing this problem. During processing, I see calls to org.hibernate.engine.Collections#prepareCollectionForUpdate for CollectionEntry[smx3.schema.PartyRole.agreementsFrom#2006094] (and other elements in the same collection) which is listed in the trace below. The collection which triggers the exception isn't consistently the same one, but seems to be localized to 4-5 different collections, I've also noticed that if I single-stepping through the process, if sometimes completes fine, which may indicate some race conditions somewhere. As I'm not entirely sure why the exception is being thrown, I'm not sure if this is a problem with Hibernate, or something wrong in our application somewhere. Is there anyway I can identify why a collection entry wouldn't have been processed (and what does "processed" actually mean?). 24.04.2009 15:57:33.180 *ERROR* [btpool0-1]
