Re: [flexcoders] Help with binding (flex 3)
I have run into the same issue. My RemoteObject calls are already set
to makeObjectsBindable so that doesn't seem to be the issue.
Basically, if i have a view that is already displaying the bound
object, then do a remoteobject call that replaces the existing bound
object with a new one, the bindings do not update. Which makes sense
as the replacement instance would not have the bindings of the current
model object set on it. Instead, I have resorted to copying the props
over to the existing model object so that the bindings and references
stay intact, using this script:
public class ObjUtil
{
import flash.utils.*;
public function ObjUtil()
{
}
public static function CopyProps(source:*,destination:*):void{
var def:XML = describeType(source);
var properties:XMLList = [EMAIL PROTECTED] + [EMAIL
PROTECTED];
for each (var property:String in properties ) {
destination[property] = source[property];
}
}
}
And is used like this:
ObjUtil.CopyProps(e.result,userModel.currentUser);
It is not immensely robust and still feels like i am missing something
in regards to binding - but this works without a whole bunch of extra
typing for each and every property that needs to be updated.
Regards,
Nik

You need to set makeObjectsBindable on your WebService object. -Josh On Mon, Aug 25, 2008 at 1:22 PM, rss181919 [EMAIL PROTECTED] wrote: I have a value object that i cast as an object. public var MyObj:Object = new MyObj All of the properties of MyObj are bindable.

Re: [flexcoders] Help with binding (flex 3)
I hope I am correct on this one, but I think the problem is the Object does not implement the IEventDispatcher Interface thus you can't do binding with an object. So maybe that is why? - Original Message - From: rss181919 To: flexcoders@yahoogroups.com Sent: Sunday, August 24, 2008 10:22 PM Subject: [flexcoders] Help with binding (flex 3) I have a value object that i cast as an object. public var MyObj:Object = new MyObj All of the properties of MyObj are bindable.
