This happens because you're trying to convert an Object from a Null Value.
In FDS2.0.1 has a little change from LCDS from transactions.
Here's a breafing on how you could do.
VObject vo = (VObject) myObject.toValueObject();
DataServiceTransaction txn =
DataServiceTransaction.getCurrentDataServiceTransaction();
if (txn != null) //this is coming through as not null..
txn = DataServiceTransaction.begin(false);
String voAss = "my-other-assembler-destination";
vo.status = DEDAppVO.Status.LOCKED.value;
vo.statusMsg = msg;
txn.updateItem(voAss, vo, null, null);
txn.commit();
To notyfiy another assembler of changes I suggest you to use the menssage
Services instead of ServicesTransaction(). Due to LCDS it will changes and
still in Beta.
Regards.

It works with FDS 2.0.1, however when I install LCDS 2.5, I get the
error below (code is following the stacktrace):
11:37:15,625 INFO [STDOUT] [Flex] [ERROR] [DataService.Transaction]
