Simple answer: put a breakpoint in updatePeopleList, which looks to be the
only place where it's set (assuming that it gets set at all):
peopleList _ (allPeople select: [:c | c matchesKey: category]) sort.
peopleListIndex _ peopleList indexOf: currentItem.
self changed: #peopleListItems
Now make a new one (I dragged one from the Objects tool). You'll see that it
gets called from initialize (indirectly):
currently: Stanwood, WA
