For problem 1: Is your SMPC called entityManager? If not are you correctly telling the entityConverter what it is called (see the wiki). If you put a breakpoint at AbstractEntityConverter:170 can you check that (a) whether the correct Lookup is used and (b) whether the correct entityManager is used - and also whether the correct class is specified and the correct id. Problem 2: Not sure - I would suggest getting Problem 1 sorted first. Problem 3: Do you mean the label doesn't display correctly? Or that the wrong item is selected?
