RE: [flexcoders] as3 - accepting a callback function name as input parameter to a function

[Gordon Smith]

It looks like you can't use Function() as a cast operator. I'm not sure
whether this is an AS3 compiler bug or not. Instead of
 
    Function(call.callbck).call(this);

try
 
    (call.callbck as Function).call(this);
 
or simply
 
    call.callbck.call(this);

Subject: [flexcoders] as3 - accepting a callback function name as input
parameter to a function



hi all,

I am implementing a actionscript function that takes in a function 
name as parameter. I want to use the passed in parameter as a 
callback function, just like mx:application creationComplete() does.

I am not able to get it to work.

In my MXML, I have:


<mx:Script>
<![CDATA[
public function initApp()
{
initApp2(initializeChart);
}

public function initializeChart()
{
....
}
]]>
</mx:Script>

In another actionscript util class, I have:

public function initApp2(callbck:Function):void 
{
var service:HTTPService = new HTTPService();
service.url = chrtdefurl;
service.addEventListener(ResultEvent.RESULT, chartDefLoaded); 
var call:Object = service.send(); 
call.callbck = callbck;
}

public function chartDefLoaded(event:ResultEvent):void
{
chartDefXML = new XML(event.result);
var call:Object = event.token;
Function(call.callbck).call(this);
}

I get error:

EvalError: Error #1066: The form function('function body') is not 
supported.
at simpleline2/chartDefLoaded()

Any ideas?

Thanks
