Hi Marco, yup once you call .commit() the factory is all done and all its internal lists of objects are cleared out, basically it's not expecting anything more to be done with it after .commit() . So because of that you need to call .getCreatedObjects() before .commit() but also after .update() has been called to make the output be generated.

I could probably change some of this in v4 to make it a bit more friendly, like if you call .getCreatedObjects() and .update() has never been called, I could probably do the update for you and maybe it would be good for the factory to retain its lists of objects even after .commit() so you could retrieve them after the commit instead of only before.
