Hi
I have tried to use the nested contexts today. I tried a
very simple thing, creating two objects one in the parent
one in the child context, then linking them together:
ObjectContext aContext = ContextManager.getNewContext();
ObjectContext childContext =
aContext.createChildContext();
Site site = aContext.newObject(Site.class);
Room room = childContext.newObject(Room.class);
r.setSite(s);
the last line throws exception:
[java] org.apache.cayenne.CayenneRuntimeException:
[v.3.0-SNAPSHOT ${project.build.date}
${project.build.time}] Cannot set object as destination of
relationship site because it is in a different
ObjectContext

ish.oncourse.server.cayenne.glue._Room.setSite(_Room.java:135)
...rest of stack trace is not important
I think it is a bug, and relating objects should be
allowed between parent/child contexts.
Another thing is that the
http://cayenne.apache.org/doc/nested-datacontexts.html
states that nested contexts are not available in ROP, is
that still?
All best
Marcin
