oldfusion, but i don't think it matters- i'm trying to take an  
actionscript object (the selectedItem of a datagrid) and cast it to

mx_internal_uid property on the list item is messing me up, it's  
the only property that comes into the VO from the datagrid that the  
VO does not have- so i got to googling.

Ah, I forgot about that issue. VOs in my projects always implement  
the IUID interface because of issues with the internal Flex controls  
(especially TileList). That's why I didn't see any issue with your  
code – in my implementation it works fine to cast it anywhere in the  
application from a dataProvider driven control.

Here's an example:

package some.package.path.vo
{
        import mx.core.IUID;
        [Bindable]
        public class MyClass implements IUID
        {
                private var _uid : String;
                public function MyClass()
                {
                }
                public function get uid(): String {
                        return _uid;
                }
                public function set uid(value: String): void {
                        _uid = value;
                }
        }
}
