[Seaside] Re: Modal dialogs that appear with their "background"

[Stephan Eggermont]

We have very few call:'s left in our apps. Most navigation is done with announcements.
We use a session subclass that has an announcer and delegate to that.

You can find sample code in both Deltawerken (DESession & DEPageChoice) and QCMagritte
(QCSession & QCPageChoice). 

You can find a pre-made image (for Pharo 2 and 3) at http://ci.inria.fr/pharo-contribution/QCMagritte
