----------------------------------------

             Summary: ROP: Cayenne tries to build a query for non committed object when using
more than 2 nested contexts
                 Key: CAY-1714
                 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:

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.query.RelationshipQuery.createReplacementQuery(RelationshipQuery.java:113)
	at org.apache.cayenne.query.IndirectQuery.getReplacementQuery(IndirectQuery.java:103)
	at org.apache.cayenne.query.IndirectQuery.route(IndirectQuery.java:86)
	at org.apache.cayenne.access.DataDomainQueryAction.runQuery(DataDomainQueryAction.java:424)
....................

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