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):

updatePeopleList
self halt.
	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):

PDA>>updatePeopleList
PDA>>selectCategory:
PDA>>userCategories:allPeople:allEvents:recurringEvents:...
PDA>>initialize
PDAMorph>>initialize
PDAMorph>>initializeToStandAlone
