Flash Builder error 1120 Access of undefined property

Question

could someone explain to me, why the Flash Builder tells me error 1120 Access of undefined property value? Thank you for every advice :-)

<fx:Script>
    <![CDATA[
        var value:Number = 5;
        if(value == 5) {

            trace("value is 5");    
        }   
    ]]>
</fx:Script>

Answer 1

You are tracing the value without any method call. You put your "if condition" in a method and call this method. I think it should definitely work.

protected function yourMethod():void{
var value:int = 5;
        if(value == 5) {
            trace("value is 5");    
        } 
}
]]>

Answer 2

You can't put random ActionScript code in your MXML file. The if statement needs to be moved into a method; kinda like this:

<fx:Script>
    <![CDATA[
    var value:Number = 5;

    protected function myMethod():void{
            if(value == 5) {

                trace("value is 5");    
            } 
    }
    ]]>
</fx:Script>

I also recommend scoping the value declaration, like this:

   public var value:Number = 5;
