Comment #6 on issue 884 by benjamin...(a)gmail.com: The Roassal presentation
should react to custom ports
I had been considering something like a #andSelect: operation similiar to
#andShow:, but your first example "on: #customPort do: [ :view :customValue
| ... ]" would work better, tying it more closely to a particular view.
Your example in Comment 5 works fine here and will do for now to integrate
into my application. thanks.
