That was what I was proposing. The usecase is the following: we have Employee with ssn, empno, lastname, firstname, and an abbreviation used to identify the employee. The autocomplete object field should accept all 5-6 different field types and query the database based on that. The list of selections should show "Lastname, first" and upon selection set the associated employee on the model. If none is found, the model should be null.
