Hope to add some value to this.
The duplicate variable error is only due to the fact that String is a native
object (don't know the correct name for this) of Flash AS3.
So you don't have to use the new key word for it.
Like this would work OK:
var arObj:Array = [{},{}]
function test():void
{
for each(var i:Object in arObj)
{
var id:MovieClip = new MovieClip()
trace("1" ,id);
id.name = "test" + Number(Math.random()).toString();
trace("2" ,id);
}
trace(i);
}

Subject: Re: [Flashcoders] Question on variable init in a for loop
no that's correct but id should be declared outside of your loop - as3 will
actually give you a duplicate variable error for putting it inside the loop.
you can also refer to your iterator (i) after the loop is done
i'd rewrite your function like this
var arObj:Array = [{},{}]
function test():void
{
var id:String;
for each(var i:Object in arObj)
{
trace("1" ,id);
id = "test" + Number(Math.random()).toString();
trace("2" ,id);
}
trace(i);
}
