Thinking About Value Lists, part 3

Welcome to the third installment in this series. We’ve been exploring various issues and behaviors in connection with 2-column value lists (VL’s), and today we’re going to look at, and propose a work around for, an issue with filtered value lists in Find mode.

All of today’s demo files feature a basic expense submission system, with each portal row representing a receipt that the submitter would like to be reimbursed for. Here it is in Browse mode:
