Title: Fixes ORA 767

The issue was that we changed our expectations about whether or not data-points was always going to be one of the data fields of a option criterion (within a student training example). This simple fix works because we ALWAYS set the name (as a unique identifier), and we set the empty selection's value to the empty string.
