Description

Steps to reproduce:

Specify a bindSetter on a checkbox's selected attribute (regardless of commitOnly param)
<mx:Script>
<![CDATA[

import mx.controls.Alert;
import mx.binding.utils.BindingUtils;

public function setBinding():void

{ BindingUtils.bindSetter(setter, binding_test, "selected") //same results as if true param is sent for commitOnly }

public function setter(testValue:Object):void

{ Alert.show("setter getting called") }

]]
>
</mx:Script>

<mx:HBox>
<mx:CheckBox id="binding_test" >

</mx:CheckBox>

<mx:Button click="setBinding()">

</mx:Button>
</mx:HBox>

Actual Results:
the "setter" function get's called twice when the checkbox has a change.

Expected Results:
It should only be called once.

Workaround (if any):
maintain state somewhere, perhaps in a static var and use the "setter" execution that reflects the changed checkbox.
