actionscript 3 - The this must be used to reference the bindadle property -

if using {result} instead of {this.result}, binding mechnism can't work. didn't find doc describing thing. using flex3.5. know reason?

<?xml version="1.0" encoding="utf-8"?> <mx:panel xmlns:mx="http://www.adobe.com/2006/mxml" width="400" height="300">     <mx:script>         <![cdata[                    [bindable]             public var result:string ="b";              function confirm():void{                 result = "changed text";             }         ]]>     </mx:script>     <mx:textinput text="{this.result}"/>     <mx:button label="confirm" buttondown="{confirm();}"/> </mx:panel> 

this not problem of binding. far know, should avoid using "result" variable name, because used components. if rename result result1, work regardless of "this" keyword.

to see difference between "result" , "this.result" can try define "result" variable static one. this:

so if there uncertainty concerning variable, "this" means member variable , not static one.

this expression can show difference between 2 variables well:

<mx:textinput text="{this.result === result}"/> 

it returns false in case.
