ActionScript Error #1024: Overriding a function that is not marked for override.

Description:
AS3 error 1024 means that Flash or Flex already has a function by that name.

Fix:
To solve Flex/Flash Error 1024 all you need to do is either correctly name the function something besides a reserved function in Flex/Flash or properly override the function. The example below shows how to solve issue number one. Notice that the good code solves Error 1024 because it doesn’t use the same name as a function that already exists in ActionScript.

Bad Code 1:

function nextFrame (e:MouseEvent):void
{
this.nextFrame();
}

Good Code 1:

function onNextFrame (e:MouseEvent):void
{
this.nextFrame();
}

This should help you resolve Flash / Flex Error #1024

Thanks and as always Happy Flashing
