Not getting an error, just getting ignored and the function is never called.
var scope:Object = this;
private var echoOrderCacheEvent:Function =
function(jstr:String):void{
Alert.show(this);
trace(scope);
}
I've tried the old pass through - but it's definitely not working properly; the
'this' that's getting called within the function is NOT the function - it's a
SubscriptionListener in the stomp framework as that's what's calling the
callback through the interface; something another dev has created and just want
to come back with enough ammunition that the callbacks aren't being set
properly:
It seems to me that he's creating another anonymous function as part of the
stomp dispatching and then everything is getting lost:
ReferenceError: Error #1069: Property com.investlab.mix.common.model::scope not
found on interbahn.SubscriptionListener and there is no default value.
