----------------------------------------
Summary: ROP: Faulting entity relationship resets uncommitted modifications made to its reverse relationship

Following sequence performed on ROP client side will reset changed patinging1->artist relationship back to old.
Artist oldArtist = painting1.getArtist(); // oldArtist->paintings are not yet faulted
painting1.setArtist(newArtist);
oldArtist.getPaintings(); // faulting paintings from db will reset painting1->artist to oldArtist back again

[jira] [Closed] (CAY-1757) ROP: Faulting entity relationship resets
uncommitted modifications made to its reverse relationship
Posted by "Andrus Adamchik (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CAY-1757?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrus Adamchik closed CAY-1757.
--------------------------------
Resolution: Fixed
Fix Version/s: 3.2M1
3.1B2
Just fixed on both 3.1 and 3.2 branches. The problem was that "local" changes in an unfaulted to-many list were merged into the fetched list after reverse relationships update. Now it is done *before*.
Thanks for the precise description of the issue. Was very easy to reproduce and locate the problematic area.
