Description

Steps to reproduce:
1. Create List control
2. Add the String "constructor" to it in some way (e.g. as in the following application)

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:List>
<mx:String>constructor</mx:String>
</mx:List>
</mx:Application>

3. Run the application

Actual Results:
Application crashes with the following error:
TypeError: Error #1034: Type Coercion failed: cannot convert Object$ to mx.controls.listClasses.IListItemRenderer.

Expected Results:
Application runs and displays the List control with the word "constructor" as an element

Workaround (if any):

The String can be replaced with a labeled Object. e.g.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:List>
<mx:Object label="constructor"/>
</mx:List>
</mx:Application>
