Error #1056, creating dynamic object

Question

Hi,
I am simultaneously creating an object and adding it to an array, perhaps ill-advisedly. The following code worked on the main timeline, but not when I moved it to the constructor of a document class:
package {
     import flash.geom.Point;
    import flash.display.MovieClip;
    public class IconTour extends MovieClip {
        var thePoint:Point = new Point();
        var defaultColor:Number;
        var overColor:Number;
        var iconCreationList:Array = new Array();
        //var xx:MyIcon;
        public function IconTour(){
            thePoint.x=50;
            thePoint.y=300;
            defaultColor=0x7dc2df;
            overColor=0x788dec;
            iconCreationList.push(this["xx"+iconCreationList.length] = new MyIcon(thePoint,"folder","Text for the folder", "Folder", defaultColor, overColor));
            for each (var iconObject:MyIcon in iconCreationList) {
                addChild(iconObject);
The following error is generated:
>ReferenceError: Error #1056: Cannot create property xx0 on IconTour.
    at IconTour()
I guess this is because xx0 isn't declared? How does one declare a dynamic object/variable?

Answer 1

Nope. No mention. However, I guess I don't need to dynamically create a variable as this works:
iconCreationList.push(xx = new MyIcon(thePoint,"folder","Text for the folder", "Folder", defaultColor, overColor));
iconCreationList.push(xx = new MyIcon(thePoint,"assignments","Text for the assignment", "Assignments", defaultColor, overColor));
where this does not:
iconCreationList.push(this["xx"+iconCreationList.length] = new MyIcon(thePoint,"quiz","Text for the quiz", "Quiz", defaultColor, overColor));
iconCreationList.push(this["xx"+iconCreationList.length] = new MyIcon(thePoint,"assignments","Text for the assignment", "Assignments", defaultColor, overColor));
AS doesn't care if I add more than one object to the array that is named xx. I probably won't be referencing xx by that name anyway, just by iconCreationList[1].
