programming flash
1

Hello All,

I was trying to create a custom ComboBox by extending the fl.controls.ComboBox.


package CustromControls
{
    import fl.controls.ComboBox;
    public class CustomCombo extends fl.ComboBox
    {
        public function CustomCombo():void
        {

        }
    }
}

and i get the error**
1017: The definition of base class ComboBox was not found.

**Any clue??

Thanks
