I stumbbled on this one too. Did someone file a bug report ?

Fabian, I discovered this a month or two ago. It appears as if iterator() does not fire the fault on relationships. That is why with your log statement everything is ok: the accessing of the productionRuns() field IS firing the fault. The iterator then works. This is a bug in the iterator implementation. The only thing you can do is either manually fire each fault or use objectEnumerator(). I use objectEnumerator().

It works fine for deliveryDefects that exist when the order is fetched from the DB. However, it fails to include a deliveryDefect that is created and then saved to the DB. Is this a known limitation of flattened relationships? Not all too important since I can of course get to it myself. Part of my first implementation looked like this: for (Iterator iter = orderItems().iterator(); iter.hasNext ();) { OrderItem anOrderItem = (OrderItem) iter.next(); // log.debug("production run count: " + anOrderItem.productionRuns().count()); for (Iterator iterator = anOrderItem.productionRuns ().iterator(); iterator .hasNext();) { ProductionRun aProductionRun = (ProductionRun) iterator.next(); if (aProductionRun.deliveryDefect() != null) deliveryDefects.addObject (aProductionRun.deliveryDefect()); } } Now, I'm using WO 5.3 with java 1.5.0, so I assumed this should work. But it fails due to iterator.hasNext() always returning false. While debugging, I introduced the log statement that is commented out above. With that in place, the iterator starts to behave correctly!? I'd really like to understand what's going on here! Is the productionRuns() fault not getting fired by the iterator? Is this intended/documented? Now I'm back to using good old Enumeration which works w/o further ado. Any comments most welcome... Fabian
