AS3 Error 1000 on Vector - actionscript-3

Question

So I've never worked with Vectors in Flash before and I wanted to write a little test application with a Vector using a custom object. But I'm getting: error 1000: Ambiguous reference to Vector when I try launching the application. I can't figure out for the life of me what's wrong. I tried not using a custom object and just instantiating a string Vector from an online tutorial and I'm getting the same thing.
Here's what I got:
package
{
import TestPlayer; // The custom player class
import flash.display.MovieClip;
public class Vector extends MovieClip
{
private var array:Array = new Array();
private var vector:Vector.<TestPlayer>;
public function Vector()
{
array[0] = [0, 0, "Bob", false];
array[1] = [1, 0, "Frank", true];
array[2] = [2, 1, "Sarah", true];
Load();
}
private function Load():void
{
var aPlayer:Player = null;
vector = new Vector.<TestPlayer>();
try
{
var numRows:int = array.length;
for (var i = 0; i < numRows; i++)
{
aPlayer = new Player();
aPlayer.playerID = array[i][0];
aPlayer.playerName = array[i][1];
aPlayer.playerTypeID = array[i][2];
aPlayer.hasProgress = array[i][3];
vector.push(aPlayer);
}
}
catch (error:Error) { }
}
}
The custom player class looks like this:
package
{
public class TestPlayer
{
private var _playerID:int;
private var _playerName:String = "";
public function get playerID():int
{
return _playerID;
}
public function set playerID(value:int):void
{
_playerID = value;
}
public function get playerName():String
{
return _playerName;
}
public function set playerName(value:String):void
{
_playerName = value;
}
[...]
}
}
I don't know if it matters, but I'm working in Flash CS5, and I have a blank FLA that imports the class. No other errors so far. Hope you can help. Let me know if you need anymore info, thanks.

Answer 1

The ambiguous reference is because you've got a naming collision. The class you've written is named "Vector", which it can't distinguish from the top-level class Vector. The fix is simple, avoid naming your classes the same as a pre-existing class.
If both classes belong to separate namespaces, you can reuse class names, as long as you use thier fully-qualified name whenever you call the class.
Assume you have a class:
package foo.bar
{
class MovieClip
...
}
You could instantiate both types of MovieClips as follows:
flashMovieClip = new flash.display.MovieClip();
myMovieClip = new foo.bar.MovieClip();
Unfortunately, both your Vector and the flash Vector exist in the top-level namespace, so (AFAIK) there's no way of removing the ambiguity without renaming your class. For simplicity sake, avoid naming collisions and you should be golden.
