Hi. I have saved an ArrayCollection to the desktop. When I read it back into
the application I get the problem that the ArrayCollection is now a collection
of Objects, not a collection of type "Player" which is the class representing
each of the elements in the ArrayCollection. Each Player class has three string
properties associated with it.

I created a function to "type" the elements of the ArrayCollection. It takes
the ArrayCollection that has been saved on the desktop as the first argument
and the "Player" class as the second argument and should return an
ArrayCollection that is typed.

Trying to figure out why it keeps throwing up an error...and whether i need a
second for loop inside the first that passes all the variables from the item
objects to the temp object.

Thanks!

private function typeCollection (collection:Object,
clazz:Class):ArrayCollection

{
var arr:ArrayCollection = new ArrayCollection();
for each (var item:Object in collection) {

var temp:Object = new clazz()
temp = item;
arr.addItem(temp);
}
return arr; //return the array collection
}

What is the error and what is clazz in:
var temp:Object = new clazz()

Hi.

The error I get is below....

ArgumentError: Error #1063: Argument count mismatch on Player(). Expected 3,
got 0. at main/typeCollection()[C:\Documents and Settings\User\My
Documents\Flex Builder 3\main\src\main.mxml:108]

Line 108 is the line var temp:Object = new clazz();

When you ask what is clazz in...clazz represents the second argument of the
typeCollection function and the argument that is passed in is the class Player
which is a class in an external actionscript file.

Actually just got it to work. The problem was....i created the Player class'
constructor function to accept three arguments (id, firstname, surname)....and
so new clazz() should have had 3 arguments....i just changed the code below and
it seems to work..

If there is a better way happy to hear!

Thanks for responding.

for each (var item:Object in collection) {

var temp:Object = new claz(a,b,c)
