Looking at ListPresenter>>whenSelectedItemChanged: aBlock it is registering aBlock on selectionHolder using #whenChangedDo: Reviewing selectionHolder "Code search...>References to it" I see that selectionHolder is initialized as an instance of SelectionHolderClass. So it seems you are expecting whenSelectedItemChanged: to be called every time the-selection-is-changed when actually it is only called once (by your application) to register the block-to-be-called when the-selection-is-changed. You don't seem to have done any such registration. cheers -ben
