When this happens, historical Proponents should no longer appear in picklists which allow users to add new Proponent(s) to a Referral. However, the Referral itself should always show all selected Proponents, whether any have subsequently been marked as historical or not.

2 typical strategies for such a problem: you load/filter/select before each show of the pick list or you create a stable cursor dependant on changes to first cursor. Second case can become hairy if # of dependencies grows, but often offers better "try it" performance as a wait in situations triggering dependancy check is often "natural".

For strategy 2: Used simple array property to store references of CAs to trigger dependant refresh on if only dependant on one cursor and biz classes calculating list of CA to refresh/update in complex cases.

The sledge hammer of strategy 1 is often fast enough - KISS is a solid reason.

Only kludgy if index is not BINARY
