Ooo, I got it! I was way off, lol.
For anyone else looking for this:
Update for Quick/BAQ Searches
The search-value-set widget does not seem to work with Quick/BAQ searches. In these instances,
use a dataview-filter-set to filter ErpSearchResults (the full quick/baq result set) on the searchResult key value which is populated automatically by a GetList based on the selected value from the user, then use a row-update and set the value to be "{ErpSearchResults.BAQTable_BAQColumn}".
You will need to use a dataview-condition to loop through the results if you do a multi-select search.
