============
I try to make Twitter Client which use Actionscript as start-up script. this actionscript is check if setting file exists.
In condition of no setting file, it show Login window, otherwise, it show Twitter feed window.
As I see in Adobe AIR Reference below,
http://help.adobe.com/en_US/AIR/1.5/devappsflex/WS5b3ccc516d4fbf351e63e3d118666ade46-7e0a. html
what I understand is that I cannot create 2 WindowedApplication because WindowedApplication does not design to communicate each other.
The reference suggust to use Window class instead of that.
So, I change WindowedApplication to mx:Window and make ActionScript to run that Window.
However, it show Error 1136 on the line which not existed.
So, below is a simple application project screenshot that reproduce this topic problem
1136: Incorrect number of arguments.  Expected 1.   TestError      line 28   Flex Problem
How can i fix this problem?
This is my short list may make more understand
* Adobe AIR - Desktop Application
* Want to open more than 1 window
* Window show up is condition of startup script
My System
* Adobe Flash Builder 4
* Flex 4
* AIR 1.5

You (or your users) shouldn't see the window when you run non-debug version of Flash Player.
Also since FP 10.1 you can handle uncaught errors like this:
        private function onCreationComplete(event:Event):void {
            if (loaderInfo.hasOwnProperty("uncaughtErrorEvents")) {
                IEventDispatcher(loaderInfo["uncaughtErrorEvents"]).addEventListener("uncaughtError", uncaughtErrorHandler);
        private function uncaughtErrorHandler(event:Event):void {
            // Do something about the error, like:
            var error:Object = event["error"];
             log.error("Uncaught Error. ErrorID={0}, Name={1} Message={2}", error.errorID, error.name, error.message);
             event.preventDefault(); // to stop the error dialog appear in debug FP
