running your code in my unit test i still get a 0 size result list.
*until* i added the following in my unittest
Dog user1 = new Dog()
//blah blah
em.merge(user1);
em.close(); <-- needed to close existing em
em = getEnityManager();
//query now executes correctly
it seems that the entity manager is not working as i expected.
by doing em.close after making objects persistent and then getting new
em, allowed the em.query to execute correctly.
i am not clear of why the em behaviours like that, given the em.find()
seem to find the correct object.
any ideas?
