Thanks Rich ;-)
You don't have compiler errors because you're assigning values to your
singleton by using the square brackets [ ] method. By doing this, at compile
time the compiler doesn't know which property you're trying to modify... The
property can be of any type or can even not exist at all, the compiler won't
bother! ;-)
To solve the problem you can use JSON as Eka previously said, or you can
modify your Settings class and make your xml processing aware of Settings'
property types.
Here is a example:
class com.mysite.model.Settings
{
private static var instance:MySettings;
public var custom_color_3:String;
public var background_image:Boolean;
public var background_type:String;
public var background_alpha:Number;
public var title_mode:String;
/*
* Private constructor
*/
private function MySettings(){
init();
}
/**
* Set the defaults values
* (otherwise properties are seen as 'undefined')
*/
private function init():Void {
custom_color_3 = "";
background_alpha = 0;
background_image = false;
background_type = "";
title_mode = "";
}
// rest of class..
}
function parseSettings(success:Boolean){
var settingsBranch:XMLNode = app_xml.firstChild;
var name:String; // will store the current node name
var value:String; // will store the current node string value
var type:String; // will store Setting's property type
var settingNodes:Array = settingsBranch.childNodes;
// iterate through setting nodes
for(var i:Number = 0; i < settingNodes.length; i++){
var settingNode:XMLNode = settingNodes[i];
name = settingNode.nodeName;
value = settingNode.firstChild.nodeValue;
type = typeof(settings[name]);
switch(type){
case "number": settings[name] = Number(value); break;
case "boolean": settings[name] = (value == "1") ? true : false; break;
default: settings[name]= value; break;
}
}
}
Hope it helps,
Julien

julien:
sure here's a sample:
class com.mysite.model.Settings {
private static var instance = null;
public var custom_color_3:String;
public var background_image:Boolean;
public var background_type:String;
public var background_alpha:Number;
public var title_mode:String;
//rest of class....
}
Here is the function where I parse the xml into the properties above,
pretty
simple:
function parseSettings(){
var settingsBranch = app_xml.firstChild.firstChild;
var c = settingsBranch.childNodes;
var num = settingsBranch.childNodes.length;
var nextBranch:XMLNode = settingsBranch.childNodes [0];
while(nextBranch){
var tagName = nextBranch.nodeName;
settings[tagName] = nextBranch.firstChild.nodeValue;
nextBranch = nextBranch.nextSibling;
}
}
and here is what the xml looks like:
<settings>
<custom_color_3>#FFFFFF</custom_color_3>
<background_image>1</background_image>
<background_type>jpg</background_type>
<background_alpha>100</background_alpha>
<title_mode>PROFILE</title_mode>
</settings>
eka: - yeah, i know xml is only a string..my problem is that i am
assigning
a string to properties that are clearly typed as something other than a
string, yet flash isnt complaining.
