I am a AS3 novice learning PureMVC and want to write code following best practices so that any other AS3 developer can pick up my code and easily understand what I did, I am tempted to do stuff as I would in JavaScript or Asp.Net/C#, but I have a feeling that might not be the best approach. Thoughts? Links? ...

So, In a Flex app I add a new GUI component by creating it and calling parent.addChild(). However in some cases, this causes an error in the bowels of Flex. Turns out, addChild actually does: return addChildAt(child, numChildren); In the cases where it breaks, somehow the numChildren is off by one. Leading to this error: RangeErro...

I'm making a small quiz-application in Flash (and ActionScript 3). Decided to use the RadioButton-component for radiobuttons, but I'm having some problems getting the word-wrapping to work. The code for creating the button can be found below. _button = new RadioButton(); _button.setStyle("textFormat", _format); _button.label = _config....
I ran across the following code in Ely Greenfield's SuperImage from his Book component - I understand loader.load() but what does the rest of do? loader.load((newSource is URLRequest)? newSource:new URLRequest(newSource)); It looks like some kind of crazy inline if statement but still, I'm a little preplexed. And if it is an if state...
Despite the rather clear documentation which says that parseFloat() can return NaN as a value, when I write a block like: if ( NaN == parseFloat(input.text) ) { errorMessage.text = "Please enter a number." } I am warned that the comparison will always be false. And testing shows the warning to be correct. Where is the corrected doc...

But at some heavy animation parts it likes to drop a couple of frames to about 22fps. Which is not that horrible. But I'm tweaking it as much as possible to k...
Here's my problem - I have some code like this: <mx:Canvas width="300" height="300"> <mx:Button x="800" /> </mx:Canvas> So the problem is that the Button inside the canvas has an x property way in excess of the Canvas's width - since it's a child of the Canvas, the Canvas masks it and creates some scrollbars for me to scroll over...

I have compiled a CSS swf file which includes embedded skins for my Flex application. In our download product, this CSS works fine. On the web, a non-Flex container is loading the Flex application, and the CSS fails silently.
