[vwnc] Handling SystemNotification

Hello. I'm having a problem trying to handle SystemNotifications. They
aren't subclasses of Exception, but of GenericException. The #on:do:
message seems to only take as its on parameter subclasses of Exception
(at least it's not working if I do on: SystemNotification do:
[something]). The reason I need to do this is beacuse BOSS throws one
of these when it finds something that can't be bossed out (like a
SocketAccessor in this case). I would like to disregard that and make
it just go on without user intervention. How can I do this?

Greetings,
FaQ

Re: [vwnc] Handling SystemNotification

Try this:

[ SystemNotification raiseSignal ] on: SystemNotification do: [ :ex | Transcript show: 'Gotcha!' ]

The problem is more likely that BOSS isn't doing what you think. If you're getting an exception, it's probably different kind of exception you need to trap.

HTH,

Martin
