Question

I going to call only “clickfun()” method i need urlPath value after success service return value. but it throws stack overflow errors. Any help please.

private function clickfun(eve:Event):String{
            languagecode = "assets/myFont_en.swf";
            Defaultlanguagecode = "assets/myFont_default.swf";
            var request:URLRequest = new URLRequest(languagecode);
            var xmlURLLoader:URLLoader = new URLLoader(request);
            xmlURLLoader.addEventListener(Event.COMPLETE,loadcompletefun);
            xmlURLLoader.addEventListener(IOErrorEvent.IO_ERROR,ioerrorFun);
            xmlURLLoader.load(request); 
            return getpath();

        }

        private function getpath():String{
            if(loadcomplete == true){
                Alert.show(urlpath);
                return urlpath;
            }else
                return getpath(); 


        }
        private function loadcompletefun(e:Event):void{
            loadcomplete = true;
            urlpath = languagecode;
        }
        private function ioerrorFun(e:IOErrorEvent):void{
            loadcomplete = true;
            urlpath = Defaultlanguagecode;
        }

Answer 1

The obvious with your remote interaction code is that loaders load data asynchronously. This means that the execution of the program continues while the loaders load data on a (virtually) different thread.

The issue is here you call getpath() right after you have started the load. This makes loadcomplete false, and the getpath function keeps recursing and the stack overflows.

What you SHOULD so is:

Let your class dispatch an event. Say you dispatch just a Event.COMPLETE event.

Tell it to the IDE like this:

Near your class declaration, add the metadata and make your class extend EventDispatcher

//Imports and package declaration

[Event(name="complete", type="flash.events.Event")]
public class YourClassName extends EventDispatcher {

    //Remaining part of class here

Then, in your loadcompletefun, add this

dispatchEvent(new Event(Event.COMPLETE));

And, in the place you call clickfun, do this:

o=new YourClassName();
o.addEventListener(Event.COMPLETE, gp);

and, declare gp as

private function gp(e:Event):void {
    trace(getpath());
    //You now have the ability to call getpath()
}
