Yes,  the closest thing might be whenSelectionChanged but nothing regarding 
click events as I see it.

In my ComposableModel the ListComposable model is 'attributes' so I did in 
initializeWidgets:

        attributes when: #doubleClick send: #onDoubleClick to: self.

where the method logs to the transcript. But nothing shows up on a double click.

I suspect that spec has to setup the morphs it creates for handling 
(double)clicks and maybe it doesn't?
