[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3782) Saving a one-to-many relationship results in unsaved transient instance exception

[Daniel Meyer (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3782?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=32502#action_32502 ] 

Daniel Meyer commented on HHH-3782:
-----------------------------------

I should also point out the testSimpleCreate() method in the EnversWithCollectionsTest class - it commits the empty set first, retrieves it from the database, then saves the item (the greeting).  This works; it's the cascading save (demonstrated by testComplexCreate()) that results in the error.

> When I create a transient set and a transient item, point them to each other, and then commit the set-with-the-item-in-it, I get this exception:  "org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing"
> This does not happen when I'm not using envers.
> The attached project's testComplexCreate() method demonstrates the error.  To run the tests, execute "mvn clean install" (requires Apache Maven, I use version 2.0.9); then target/surefire-reports/com.example.db.EnversWithCollectionsTest.txt will have the stack trace.
