[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-7247) Bug on flushing context with modified non initialized lazy collection ( It works fine on hibernate 3.5.6 )

Hood Wilson Gusso Silva commented on HHH-7247:
----------------------------------------------

Oh I forgot to inform that this error occurs only when we have cascade DELETE_ORPHAN.
( the exception is thrown from AbstractPersistentCollection.getOrphans() when trying to run a ForeignKeys.getEntityIdentifierIfNotUnsaved() )

>             Project: Hibernate ORM
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 3.3.2
>         Environment: This problem occurs on hibernate 3.3.2 and 3.3.1 
> ( The latest JPA1 hibernate implementations I've found )

> This is a quite trick problem that only occurs on modified lazy collections that aren't initialized
> ( Like when you do a add() operation without any previous size() or get() or toString() ... )
> I think that it will be easier to show it by a commented source.
> I made a little database (with only 3 simple tables to make possible to reproduce the error.) + a maven project 
> The maven project have 2 file called pom33.xml and pom35.xml so it's possible to easily see how the error occurs on 3.3.2 but not on 3.5.6
> the script to recreate the problem is available within the project too.
> BTW the source do a rollback ( So it won't change the database ).
> If you want changes on db it will be necessary to change the rollback() to commit()
