Look like the suspect is in SystemNavigation and is here (change "class" to "behavior" when creating the Method reference): addSelectorsReferingTo: aSymbol in: class to: sortedSenders special: special byte: byte {class. class class} do: [:behavior| (behavior thoroughWhichSelectorsReferTo: aSymbol special: special byte: byte) do: [ :sel | sortedSenders add: (MethodReference class: behavior selector: sel) ]] ----------------- Benoit St-Jean A standpoint is an intellectual horizon of radius zero.

The first version used SystemNavigation#allSendersOf: which sometimes returns wrong results (I think). For example: senders := (SystemNavigation default allSendersOf: #methodsFor:). senders size. "answers 18"senders collect: [:aReference| aReference compiledMethod]. debuggers open as ChangeSet#scanCategory doesn't exist (it's on the class side but allSendersOf: returns #scanCategory reference on class side and instance side). With #allReferencesTo: senders := (SystemNavigation default allReferencesTo: #methodsFor:).senders size. "answers 16" Is this a bug in #allSendersOf: or I don't understand ?
