Double click datagrid?

Hello,

CS3/AS3.0

Has anybody here found a way to overwrite the default functionality of the datagrid component, so cells will only be editable after they are double-clicked? I’ve tried implementing this dude’s method (http://blogs.adobe.com/aharui/general/) but to no avail. I get a message that says:

“1020: Method marked override must override another method.”

in reference to this method:

        
override protected function mouseDoubleClickHandler(event:MouseEvent):void {
            super.mouseDoubleClickHandler(event);


            // simulate a click (just calling the mouseUpHandler wont work)
            super.mouseDownHandler(event);
            super.mouseUpHandler(event);
        }

Any help is appreciated. Or if you know of anybody else who’s created a double click functionality for the datagrid.
