Re: [flexcoders] Change Object Reference
Hi, I would think that setting; vo = null; then vo = someNewObject would unlink the reference. OR vo = new Object(); then vo = someNewObject Peace, Mike On 6/3/07, Kevin [EMAIL PROTECTED] wrote: This may be a simple question, but it's stumping me.

Re: [flexcoders] Change Object Reference
Rather than just assigning the model.someObject directly to the vo object, you may first need to instantiate it with: var vo:Object = new Object(); The assign the model.someObject to it: vo = model.someObject; When you then assign a different object to it, it should leave model.someObject alone and just use the newly assigned object.

thanks.

Re: [flexcoders] Change Object Reference
i couldn't get either of these solutions to work. When I reset the vo variable to nul (or new Object), it still modifies the object on the model. I could be doing something wrong, but for now, i decided to instantiate an entirely new super class each time the vo changes. I'll look into this a little more and see if I can do what I want... thanks, Kevin On Jun 3, 2007, at 9:33 AM, Jurgen Beck wrote: Rather than just assigning the model.someObject directly to the vo object, you may first need to instantiate it with: var vo:Object = new Object(); The assign the model.someObject to it: vo = model.someObject; When you then assign a different object to it, it should leave model.someObject alone and just use the newly assigned object.

Afaik this is not possible. I guess your example is incomplete, or ? Cheers, Ralf. On 6/3/07, Kevin [EMAIL PROTECTED] wrote: This may be a simple question, but it's stumping me.

Hey Kevin,
See if this makes sense in your configuration:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
creationComplete=initApp()
layout=vertical
mx:Script
![CDATA[
private var obj1:Object = new Object();
private var obj2:Object = new Object();
[Bindable] private var objRef:Object = new Object();
private function initApp():void {
obj1.text = test1;
obj2.text = test2;
txtObject0.text = obj1.text;
txtObject1.text = obj2.text;
objRef = obj1;
}
private function switchObjects(event:Event):void {
objRef = obj2; // testing reassigning of objects
txtObject0.text = obj1.text;
txtObject1.text = obj2.text;
}
]]
/mx:Script
mx:Panel id=myPanel width=538 height=334 layout=absolute
mx:VBox width=100% height=100% x=10 y=10

You'll see objRef taking on the new object values and leaving obj1 alone
when you switch object assignments.

RE: [flexcoders] Change Object Reference
Is it just me? References don't need unlinking. The original example
should just work. Kevin, can you post your code so we can see what
you're trying to do?
