Hello, I was wondering what more experienced users than myself thought of the idea of an explicit Spec "connection point" to a domain model object similar to Dolphin's "showOn:" method, like: CounterApp showOn: counter. This would perhaps trigger something like Dolphin's Presenter>>model: message (although I've always found the use of "model" confusing when there are so many "models" involved.) after the widgets had been created: ComposableModel>>initializeBindings: anObject In many cases, if your domain model uses ValueHolders as well (like Spec does), making a connection could just mean replacing the Spec ValueHolder with your domain ValueHolder so changes to the domain model would automatically propagate to the UI presentation without providing explicit code in ComposableModel>>initializePresenter. However, since I am still trying to understand and learn Spec, it's quite possible I am missing some key point and there are reasons not to explore this line of thinking! Thank you, Rob
