Thanks for your response Wolfgang, Yes, getMyUnits() returns an ArrayList<Unit>; I don't believe this likely to be the problem since I have these in other rules that are functioning. More debugging shows that the error is occurring in routine Value.stringValue. Do you see anywhere where I am trying to get the string value of a list?
