This is not related to the NPE issue. It's related to my earlier comment
about updating arrays of simple fields. Right now, if you try to update an
array that does not contain records, it won't do anything because of the field
name we're giving here. If you think that should be a separated JIRA and/or
addressed differently, let me know. (I added a unit test to update an array of
integers)
