    [ https://issues.apache.org/jira/browse/FLEX-15159?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14530287#comment-14530287 ] 

Gareth Daniel Smith commented on FLEX-15159:
--------------------------------------------

Any change this could be re-opened?

This sort of thing makes Flex confusing to use (because this behaviour is unexpected) and slow (because I choose to use ArrayCollection instead of ArrayList purely because the former has a nicer API, despite it having more overhead).

I would be willing to contribute a patch.

> 1. Make sure your imports are correct:
> import mx.controls.Alert;
> import mx.collections.IList;
> import mx.collections.ArrayList;
> 2. Create a function which looks like:
> private function foo() : void
> {
> 	var aList : IList = new ArrayList();
> 	aList.addItem("foo");
> 	
> 	for each (var s : String in aList)
> 	{
> 		Alert.show(s);
> 	}
> }
> 3. Call the function
>  
>  Actual Results: No message box is shown
>  
>  
>  Expected Results: A message box with the text "foo"
>  
> This becomes a problem when you don't know what implementation an IList variable will be bound to, ref: http://bugs.adobe.com/jira/browse/SDK-14837
>  Workaround (if any): use the for loop instead
> for (var i : int = 0; i < aList.length; i++)
