sorry for the * it was a copy and past problem.
Thanks Shaun, for your explanation.
I need the for in loop not to add new properties to my object, but to
iterate through its properties and add them to a new object.

The "for in" loop only iterates over dynamic properties. Not fixed.
You can either make your object dynamic.
public dynamic class ItemVO implements IValueObject
Or you have to use flash.utils describeType to get an XML representaion
(minus static properties, I think).
Dynamic objects can make life easier in a lot of ways, especially with
item renderers and editors, but beware the downside. You can set and
access properties that are not part of the class, same as you can with a
Plain Old Actionscript Object instance (POAO ;). So a simple typo could
create real hassles, rather than being caught be the compiler.
Ie) you can do the following:
var item:ItemVO = new ItemVO();
item.property_that_doesnt_exist = "a value";
or
var s:String = item.property_that_doesnt_exist;
