It looks like this:https://s3.amazonaws.com/steverstuff/items.pngIf I hit a specific selection, say "Item B", how can I make smalltalk run an arbitrary piece of code? (ie: "Transcript show: 'got here'"). Method "whenSelectedItemChanged" should, in theory, do this. It is mentioned in the [[https://benjamin.vanryseghem.com/projects/spec/docs/example/#protocolList][spec]] tutorial, but for some reason it's not executing. Did a new verion of spec change things since the documentation was written? There doesn't seem to be a spec community where I can ask the question.
