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.

> 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.
