[Freeswitch-users] firing events from javascript - working example needed

Wed Jan 21 13:59:44 PST 2009

RESOLVED!
Stephen, when using event sub-classes you need to specify the subclass
when subscribing to listen to the events. I added a small entry to the
wiki page that I hope makes it clear:
http://wiki.freeswitch.org/wiki/Javascript_Event#Subscribing_To_Custom_Events

Let me know if you have any more questions.
-MC

P.S. - I will follow up with Lua and Perl and make sure that the wiki
is clear on how to subscribe to events. it looks like the default for
Lua is not to have an event subclass but the default for JavaScript
does have an event subclass... :)
