[flexcoders] Binding to a subclass of a proxy object

[Austin Kottke]

Hi,

    Here's what I'm trying to do. Load in an xml file, assign this to a 
settings singleton which extends flash_proxy and then bind to these 
properties.

    Essentially:

    public function setupXMLProxy( contentToProxy:XML ):void {
            logger.debug( "setupXMLProxy() called." )
            var content:XML = contentToProxy;
           
            for each( var node:XML in content.Text ) {
                logger.debug("node: " + [EMAIL PROTECTED]  +" == " + node);
                this[ [EMAIL PROTECTED] ] = node ;
            }
         
        }

The singleton proxy now has a bunch of variabels that can be referenced 
like

var myProp:String = LocaleMgr.getInstance().propertyFromXML

Which retrieves the translations.

This works.

What doesnt work is binding to these properties from other mxml files. 
My binding method in the singleton is the following:

public function bind( object:Object, propertyName:String, param:String = 
"text" ):void {
            var w:ChangeWatcher = 
ChangeWatcher.watch(LocaleMgr.getInstance(), propertyName, null, false);
       
            if (w != null)
            {
                var assign:Function = function(event:*):void
                {
                    object[param] = w.getValue();
                };
                w.setHandler(assign);
                assign(null);
            }
   }

Basically I took the code from BindingUtils and stuck it in my static 
instance.

This works for a single property, but it does not work automatically if 
I assign a property to the static instance.

There is no updating occurring unless I directly reset the binding which 
defeats the purpose.

Anyone have any bright ideas on this?
