Hi Bruno, I just wrote a small test-case which used:
Source -> Middle ->> Target Using source.getMiddle().getTargets() succeeds, but using source.getFlattenedTargets() fails. The faults are never triggered so the data is never faulted in from the database. This seems like a bug. Two options: 1) Add a prefetch to your query to force the Target to be present: query.addPrefetch(Source.FLATTENED_TARGETS_PROPERTY); 2) Add a cover method in Source.java to fetch Targets lazily and not even model the flattened relationship. Hope that helps for now. mrg On Fri, Sep 23, 2011 at 12:17 PM, Bruno René Santos <brunor...@holos.pt> wrote: > Hi Michael, > > I dont mind having read-only relationships. > The problem here is that I have a flattened relationship that returns an > empty set when its unflattened counterpart returns values.... > > Thanx > Bruno > > On Fri, Sep 23, 2011 at 4:26 PM, Michael Gentry <mgen...@masslight.net>wrote: > >> Hi Bruno, >> >> I got the screenshot.
