Creating custom events in a domain.

Hi Squeakers,

I am working an a project where we have a domain. this domain should
not know the classes outside the world, so to communicate the domain
should fire an event where the classes outside the domain could react
to.
How could this be done? I didn't find anything about it in the wiki..

Kind regards,

Mispunt

Hi Mispunt,

you may try using the Announcements framework. Lukas Renggli recently
blogged about it at http://www.lukas-renggli.ch/blog/decoupling

        Ciao,
