Re: [Flashcoders] central up to date data
Hi Tom, It's a bit hard to tell without seeing the code. If your app class and your menu class, etc. are each creating their own extension of utils, then how are those subclasses communicating? Are they calling some update function in the super class? It sounds like you need to use a singleton, and give it an update() method that any class can access. That way you know all your classes are updating the same instance. Here are great examples of singletons: http://www.gskinner.com/blog/archives/2006/07/as3_singletons.html Hope that helps, Bob Tom Huynen wrote: Hi List!

Re: [Flashcoders] central up to date data
You're probably running into this because you're attempting to use
instance variables like static variables.
If you're just storing one variable, you can use a single static
variable in your ancestor class.
If you wanted to access this variable akin to a local property of
specific extended child class instances, you could wrap it in an
accessor. I'm thinking of something like the following.
//
// In Utils.as:
private static var _colorValues:Array;
public function get colorValues():Array {
return Utils._colorValues;
}
public function set colorValues(newVal:Array):void {
Utils._colorValues = newVal;
}
//
// In Application.as, which extends Utils.as:
// Inside some function, let's get _colorValues:
trace(this.colorValues);
//
This is totally untested, just off the top of my head.

You may want to look into using a Singleton or static class, depending on how you have things implemented and what the desired functionality is. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tom Huynen Sent: Friday, October 19, 2007 5:41 AM To: flashcoders@chattyfig.figleaf.com Subject: [Flashcoders] central up to date data Hi List!
