Hi Ian, Sorry, it's not very clear in all that garbled code.
If you make a new instance of B each time then only 1 request would be made to each instance. The event could then be sent to the same listener for each instance but with the appropriate parameter as part of the (custom) event. If you think about it, it's very similar to how Delegate works by creating a "holding" area but now you have a (custom) event dispatched which is fully typed. I suppose you have to decide if it's worth the extra time or not based on what you're doing. :) Sunil -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ian Thomas Sent: 25 July 2007 16:10 To: [email protected] Subject: Re: [Flashcoders] AS3 Events Hi Sunil, That won't work if multiple requests are filtering through the same B - which is where the whole problem starts from. :-) Because request 2 overwrites the contextInfo written by request 1 - which is why both Muzak (and I) suggested B has an internal list of contextInfos. But that gets more tricky... But thanks!
