Marcin Skladaniec commented on CAY-538:
---------------------------------------
I found a test which covers this scenario, and it works in m5
(org.apache.cayenne.remote.RelationshipChangeTest)
I think this task can be closed.
> Relationship not refreshed before committing the context.

> Key: CAY-538
> URL: https://issues.apache.org/cayenne/browse/CAY-538
> Project: Cayenne
> Issue Type: Bug
> Components: Cayenne Core Library
> Affects Versions: 1.2 branch
> Environment: I think any platform, but tested on os x and freebsd.
> Cayenne 3t
> Reporter: Marcin Skladaniec
>
> I have two sites : site1 and site2 and a room linked to site1
> If I change the relationship so the room links to site2, than before I commit
> the changes both sites are linked to the room.
> The code
> {
> Expression expression =
> ExpressionFactory.matchExp(CSite.NAME_PROPERTY, "site1");
> SelectQuery query = new SelectQuery(CSite.class, expression);
> List list = context2.performQuery(query);
> CSite tempsite1 = (CSite)list.get(0);
>
> expression = ExpressionFactory.matchExp(CSite.NAME_PROPERTY,
> "site2");
> query = new SelectQuery(CSite.class, expression);
> list = context2.performQuery(query);
> CSite tempsite2 = (CSite)list.get(0);
>
>
> expression = ExpressionFactory.matchExp(CRoom.NAME_PROPERTY,
> "room");
> query = new SelectQuery(CRoom.class, expression);
> list = context2.performQuery(query);
> CRoom temproom = (CRoom)list.get(0);
>
>
> logger.info("site 1 rooms");
> List rooms = tempsite1.getRooms();
> for (int i=0; i<rooms.size();i++) {
> logger.info("\troom "+i+" :
> "+((CRoom)rooms.get(i)).getName());
> }
>
> logger.info("site 2 rooms");
> rooms = tempsite2.getRooms();
> for (int i=0; i<rooms.size();i++) {
> logger.info("\troom "+i+" :
> "+((CRoom)rooms.get(i)).getName());
> }
> logger.info("(here relationship is modified)");
> temproom.setSite(tempsite2);
>
> logger.info("site 1 rooms");
> rooms = tempsite1.getRooms();
> for (int i=0; i<rooms.size();i++) {
> logger.info("\troom "+i+" :
> "+((CRoom)rooms.get(i)).getName());
> }
>
> logger.info("site 2 rooms");
> rooms = tempsite2.getRooms();
> for (int i=0; i<rooms.size();i++) {
> logger.info("\troom "+i+" :
> "+((CRoom)rooms.get(i)).getName());
> }
> }
> produces output :
> site 1 rooms
> room 0 : room
> site 2 rooms
> (here relationship is modified)
> site 1 rooms
> room 0 : room
> site 2 rooms
> room 0 : room
> I can publish a small project reproducing this bug.
