as3 - Constructor Error

I've got (to me) a strange error. As far as I can tell I'm doing everything correct, however I keep getting the error bellow.

ArgumentError: Error #1063: Argument count mismatch on Enemy(). Expected 2, got 0.

As you can see, when initializing my class Enemy it expects two arguments and gets one. However, as far as I can tell it's not the case.

Where it is called.

function startHandle(evt:MouseEvent):void{
  enemy = new Enemy(1090, 189);
  gotoAndStop(2);
  Player.stop();
  currentLevel = 1;
}

Then the Enemy class

public function Enemy(xLocation:int, yLocation:int){
        trace(xLocation);
        trace(yLocation);
        // constructor code
        x = xLocation;
        y = yLocation;
        trace(x);
        trace(y);
}

The output I get from this is as follows.

1090

189

1090

189

ArgumentError: Error #1063: Argument count mismatch on Enemy(). Expected 2, got 0.

at flash.display::MovieClip/gotoAndStop()

at Project_fla::MainTimeline/startHandle()

As far as I can tell it gets the two values, knows it has them, sets them. But still gives an error. Anyone got an idea?

Most likely you have a pre-placed enemy on some frame. Since the default constructor for any DisplayObject descendant wants 0 arguments, anything created in Flash GUI makes Flash compiler to make a constructor call with 0 arguments. To circumvent this (and find that pesky enemy that throws you up) give default values for the constructor like this:

public function Enemy(xLocation:int=0, yLocation:int=0){

And watch when an enemy will appear at (0,0), debug that point and eliminate creation of any unneeded enemy instances.
