[flexcoders] dynamic bindable objects and extending Proxy

[Justin J. Moses]

Who has experience extending Proxy?

I have successfully created dynamic bindable objects by both extending
Proxy and implementing EventDispatcher - this solution is available
around town, and I'm sure you've seen it. 

However, if I use this dynamic object as a row in a dataProvider in a
Datagrid say, then the grid will call the object's toString() property.

My question is, how do I successfully implement Proxy's
"callProperty()" method? 

My solution below was simply to return an toString() iteration of all
the properties, but I don't think this is the best way to do it. 


override flash_proxy function callProperty(name:*, ... rest):* 
{
        if (name.localName == "toString")
        {
                var str:String = "";
                                
                for each (var field:String in this)
                {
                        if (field != null)
                          str += field.toString();
                }
                                
                        return str;
        }       
}

Anyone know the best practice in this case?

thanks,
