Description

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:

org.apache.cayenne.CayenneRuntimeException: [v.3.1M4-SNAPSHOT Jun 15 2012 06:55:01] Can't build a query for relationship 'gallery' for temporary id: <ObjectId:Painting, TEMP:000001CA37BA0001>

at org.apache.cayenne.access.DataDomainQueryAction.runQuery(DataDomainQueryAction.java:424)
....................

Persistence state of artist and painting objects by that moment will be COMMITTED.
