Re: [flexcoders] Binding from Actionscript
Hi Ralf ! Im fine thank you! ( I will mail you personally at gmail )
Thanks for your help. I finally got that binding working! Paul sent me
some stuff (same stuff posted in flexcoders I think) and "with some
time" I managed to make it work.
In summary, I was creating the binding in the wrong place. I was
creating the binding in the class constructor and creating it in the
"createChildren" protected method made the trick, and the binding was
not a binding to a display object! :/ It was a binding from an object in
the model to a setter function in the class.
Anyway, thanks to everyone and specially thanks to Ralf and Paul in the
EMEA Adobe Consulting team.
Cheers,
Alberto

RE: [flexcoders] Binding from Actionscript
Hi Alberto,
>From what I can tell, it seems you use bindSetter to bind to an ordinary
function. If you want to bind to a 'set' function you actually need to
use bindProperty (because 'set' functions are treated as properties).
See the demo app I have pasted below that shows both approaches.

Subject: [flexcoders] Binding from Actionscript
Hello all,
I have an MXML component that has an mxml binding to a setter function
like this:
and a setter function defined :
private function set handleDestroy( destroy:Boolean ): void {
// some code
}
This works 100% but I need to create this binding in an actionscript
component; I have tried the following:
BindingUtils.bindSetter( handleDestroy, model.podManager.getPod(
this.mypodId ), "destroy", false );
and having the same setter function. It complains about the setter
function. If I remove the "set" keyword (on the setter function) it
compiles but does nothing ( the binding doesnt seem to enter the
function )
How can I create this binding from actionscript? Can someone give a
working example on how to create a binding to a setter function in
actionscript? It should be easy but I have found no documentation at all
on this. I need the help of an expert.
Thank you very much.
Alberto

Re: [flexcoders] Binding from Actionscript
Hi Alberto,
how are you doing?
I'm not sure, why it works in the first place. I can't get it to run
it with the following code.
What is different in your code?
snip
http://www.adobe.com/2006/mxml"; layout="absolute">
snip
package
{
public class Model
{
[Bindable]
public var podManager : PodManager;
public function Model()
{
podManager = new PodManager();
}
private static var instance : Model;
public static function getInstance() : Model
{
if( instance == null ) instance = new Model();
return instance;
}
}
}
snip
package
{
import mx.collections.ArrayCollection;
import flash.events.Event;
import flash.events.EventDispatcher;
public class PodManager extends EventDispatcher
{
private var pods : ArrayCollection;
public function PodManager()
{
pods = new ArrayCollection();
pods.addItem( new Pod("pod0"));
pods.addItem( new Pod("pod1"));
pods.addItem( new Pod("pod2"));
pods.addItem( new Pod("pod3"));
}
public function getPod( podId : int ) : Pod
{
return pods.getItemAt( podId ) as Pod;
}
}
}

package
{
public class Pod
{
public var name : String;
[Bindable]
public var destroy : Boolean;
public function Pod( name : String )
{
this.name = name;
