Hi Bryce,
Thanks for posting your model objects. I'm not able to reproduce the
exception you're reporting, but then again I'm just guessing at how you're
populating your objects and persisting them. Here's what I did:
Bundle b = new Bundle();
RatePlan rp = new RatePlan();
rp.setPricingModel(PricingModel.BOTH);
b.setRatePlan(rp);
b.setPricingModel(PricingModel.PER_GUEST);
BundledActivity ba = new BundledActivity();
ba.setDay(3);
ActivityFK activityFK = new ActivityFK();
activityFK.setName("harold");
activityFK.setPricingModel(PricingModel.PER_UNIT);
ba.setActivity(activityFK);
RatePlan anotherRatePlan = new RatePlan();
ba.setRatePlan(anotherRatePlan);
b.getActivities().add(ba);
beginTxn();
pm.makePersistent(b);
commitTxn();
If you can tell me how what you're doing differs from what I'm doing I can
investigate further.
Thanks,
Max
