access of undefined property from Flash to Flashbuilder

Question

searched whiled but I couldent find the answer here on Stack so I hope someone can help me.

I trying out Flash prof CS6 and Flashbuilder, I have created in Flash a Movieclip called square_mc and instantiated it with the name square.

I have linked a class file called Main.as to FLash builder, and in flash builder I write:

   package
{
    import flash.display.MovieClip;
    import flash.events.MouseEvent;

    public class Main extends MovieClip
    {
        public function Main()
    {
            super();

            circle.addEventListener(MouseEvent.CLICK, onToolClick);
    }

    function onToolClick(event:MouseEvent):void{
        trace("klickade på ontoolclick");
        }

    }
}

in Flash builder I get the warning "access of undefined property circle" But when I run it , it works like a charm.

Im guessing its just that Flashbuilder don't know that I already instantiated it with the name circle in Flash, and therefor gives the warning.

Is there a way I can make Flashbuilder understand that its there and working?

Answer 1

Option 1: To remedy this, I usually uncheck "Automatically Declare Stage Instance" in the ActionScript Settings (File > ActionScript Settings) in Flash CS6. Then in Flash Builder declare the MovieClip you have on the stage in Flash CS6 as such:

package
{
    import flash.display.MovieClip;
    import flash.events.MouseEvent;

    public class Main extends MovieClip
    {
        public var circle:MovieClip; // manually declare circle

        public function Main()
    {
            super();

            circle.addEventListener(MouseEvent.CLICK, onToolClick);
    }

    function onToolClick(event:MouseEvent):void{
        trace("klickade på ontoolclick");
        }

    }
}

Option 2: If you don't want to manually declare all the movies on the stage, option 2 is to create a reference to circle as a separate variable for Flash Builder:

package
{
    import flash.display.MovieClip;
    import flash.events.MouseEvent;

    public class Main extends MovieClip
    {
        private var _circle:MovieClip;

        public function Main()
    {
            super();
            _circle = this.getChildByName( "circle" ) as MovieClip;
            _circle.addEventListener(MouseEvent.CLICK, onToolClick);
    }

    function onToolClick(event:MouseEvent):void{
        trace("klickade på ontoolclick");
        }

    }
}

This should stop Flash Builder from giving you the error message :)
