URL: https://issues.apache.org/jira/browse/CAY-1714
Project: Cayenne
Issue Type: Bug
Components: ROP
Affects Versions: 3.1M3
Reporter: Dzmitry Kazimirchyk
Code describing the problem:
CayenneContext context = cayenneService.getContext();
Artist a = context.newObject(Artist.class);
a.setArtistName("a");
ObjectContext child = context.createChildContext();
Painting p = child.newObject(Painting.class);
p.setPaintingTitle("p");
p.setToArtist(child.localObject(a));
child.commitChangesToParent();
p.getToGallery(); // this will throw an exception
On the last line following exception will be thrown:
