TypeError: cl is not a constructor

Hi,
I converted my code to Haxe using as3hx tool.
I am getting this error
Error Message:
TypeError: cl is not a constructor
at Function.Type.createInstance (DocumentClass.js:5297)
Actual code:

import com.freeactionscript.weaponsystem.weapons.LaserSingle;
class Main extends MovieClip
{
 public function new()
    {
               singleTurret = new ProjectileSingle("gun 1", _weaponManager, 100, 275, 90);  
    }
}
class ProjectileSingle extends AbstractWeapon
{
    public function new(id : String, manager : WeaponManager, x : Float, y : Float, rotation : Float)
    {
        super(id, manager, x, y, rotation);
        }
}

Help me what is going wrong

Please paste the code after conversion

it’s caused by code in attachSkin, I can’t help much more right now but try debugging class paths there
