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:
<mx:Binding source="model.podManager.getPod( mypodId ).destroy"
destination="handleDestroy" />
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
