quickAssign() wired lt.combobox.init() with an onSelect callback, but combobox only supports the multi-select onChange(selected[]) contract — onSelect is never invoked, so _quickAssignUserId stayed undefined no matter what the user picked and Quick Assign always showed "Please select a user from the list." Switched to lt.typeahead.init(), which does support onSelect, matching the already-working Bulk Assign modal.
