Re: [flexcoders] Flex2 flash_proxy/Proxy getProperty and Binding
Well, I was just in this classroom the other day. If I get your question correctly..
Add;
use namespace flash_proxy;
right under the import flash.util.flash_proxy.
If you got this code from an example, it was missing the use statement.
I missed this also!, Once the use is in there it works great!

Proxy Class:
package {
import flash.util.flash_proxy;
import flash.util.Proxy;
dynamic public class SomeClass extends Proxy {
public var _dynamicAttributeArray:Array;
public function SomeClass() {
_dynamicAttributeArray = new Array();
}
flash_proxy override function getProperty( name : * ) : * {
return _dynamicAttributeArray[ name ];
}
flash_proxy override function setProperty(name:*, value:*):void {
_dynamicAttributeArray[ name ] = value;
}
}
}
Now if I have:
?xml version=1.0 encoding=utf-8?

mx:VBox width=100% height=100%

AW: [flexcoders] Flex2 flash_proxy/Proxy getProperty and Binding
Hi,
you have to use namespace
as well. Here is an example of a SortedList I use in testproject. You can
enumerate the ListKeys with for in and the Items with for each in.

package Helper {
import
flash.util.Proxy;
import
flash.util.flash_proxy;
use
namespace flash_proxy;
public
class SortedList extends Proxy {
private
var _Values:Object;
private
var _Keys:Array;
private
var _Sorted:Boolean;
private
var _Count:int;
public
function Add(key:String, value:Object):void {
if(
_Values.hasOwnProperty(key) ) throw new Error(Key allready
exists.);
_Values[key]
= value;
_Count++;
_Sorted
= false;
}
public
function Clear():void {
_Values
= new Object();
_Sorted
= false;
_Count
= 0;
}
public
function ContainsKey(key:String):Boolean {
return
_Values.hasOwnProperty(key);
}
public
function get Count():int {
return
_Count;
}
public
function Item(keyindex:Object):Object {
return
this.getProperty(_GetKey(keyindex));
}
public
function Key(index:int):String {
if(
index 0 || index = this.Count ) throw new RangeError();
return
this.Keys[index];
}
public
function get Keys():Array {
if(
!_Sorted ) {
_Keys

for(var
_Key:String in _Values) {
_Keys.push(_Key);

_Keys.sort();

_Keys;

else

if(

flash_proxy/Proxy getProperty and Binding
The sample code is located
below. I am trying to find a way to bind
dynamic attributes (when using Proxy class).
I can't get the dynamic
properties to bind, any suggestions or help would
be appreciated.
