Description

Steps to reproduce:
1. Create a new MXML file with the following code:

<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" myNewProperty="blah">
<fx:Script>
<![CDATA[
public var myNewProperty:String;
]]
>
</fx:Script>
</s:Group>

Actual Results:
Cannot resolve attribute 'myNewProperty' for component type spark.components.Group.

Expected Results:
The "myNewProperty" is defined on the subclass and we should be allowed to set it here. This also happens for setters as well.

Workaround (if any):
Don't set the property in MXML, but create a function to do this and call it during a lifecycle event (creationComplete or something like that). However, when doing binding, it sucks to have to call BindingUtil, but that will still work as a work-around.
