------------------------------
Comment: was deleted
(was: A tempory proposed patch which doesn't delete modifiedState when we merge
deletedStates of ChangeLog.

> Key: JCR-2626
> URL: https://issues.apache.org/jira/browse/JCR-2626
> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: jackrabbit-core
> Affects Versions: 1.6.1
> Environment: Windows XP
> Reporter: alban seurat
> Priority: Critical
>
> I've created a test case to reproduce the issue.
> In short, I have 2 artifacts where one has a reference on the second one. I
> want to copy/delete the second one and update the reference, save my
> operation and do a copy/delete of the first artefact afterward.
