[flexcoders] Custom renderer for column's header

[markgoldin_2000]

I have the following code:
import mx.core.UIComponent;
public class hoursSymbolsHeaderRenderer extends UIComponent
{
        public function hoursSymbolsHeaderRenderer()
        {
                super();
        }
        
}
But when I do:
var hoursSymbolsHeaderRenderer:ClassFactory = new ClassFactory;
hoursSymbolsHeaderRenderer = new ClassFactory
(hoursSymbolsHeaderRenderer);
I get:
1067: Implicit coercion of a value of type mx.core:ClassFactory to an 
unrelated type Class.

What am I doing wrong?

Thanks
