Greetings!

I’ve banging my head against the wall for a few days now about this problem:

Code:

\<?xml version=“1.0” encoding=“utf-8”?\>  
\<mx:Application  
xmlns:mx=“[http://www.adobe.com/2006/mxml](http://www.adobe.com/2006/mxml)” creationComplete=“init()”  
layout=“absolute”\>  
\<mx:Script\>  
\<![CDATA[  
import mx.collections.ArrayCollection;

```
        public var myArr:ArrayCollection = new ArrayCollection(new Array("1","2","3","4","5"));
        
        public var myTest:ArrayCollection = new ArrayCollection()
        
        public function init():void{
            myTest = new ArrayCollection(myArr.source);
            myTest.removeItemAt(2);
            trace(myTest.length);
            trace(myArr.length);
        }
    ]]&gt;
&lt;/mx:Script&gt;

```

\</mx:Application\>

the code above results in an output of

Code:

4  
4

But I want it to result in  
Code:

4  
5

I believe that because you are pointing it to the arrayCollection’s source it isn’t making a new instance of that source, it is using the same source for both arrays, so when you change one both arraycollections change. Change the line to:

myTest = new ArrayCollection(myArr.toArray());

and that should work.
