ActionScript 3 Error #1061: Call to a possibly undefined method gotoAndStop through a reference with static type flash.display:DisplayObject.

ActionScript 3 Error #1061: Call to a possibly undefined method gotoAndStop through a reference with static type flash.display:DisplayObjectContainer.

ActionScript 3 Error #1061: Call to a possibly undefined method gotoAndStop through a reference with static type flash.display:Stage.

Description:
AS3 error 1061 will pop up when you trying to referencee an object from within a function that receives an Event. When you do this it will reference the DisplayObject or if you call out to this.parent rather than event.target.parent it will reference the DisplayObjectContainer which doesn’t have a lot of methods with it.

Fix:
One solution to solve Flex/Flash Error 1061 is to make sure that you are using the event that is passed as the target by using

Bad Code 1:

getStarted_btn.addEventListener(MouseEvent.MOUSE_UP,gotoFrame10 );

function gotoFrame10 (e:MouseEvent)
{
this.parent.gotoAndStop(10);
}

Good Code 1:

getStarted_btn.addEventListener(MouseEvent.MOUSE_UP, gotoFrame10);

function gotoFrame10 (e:MouseEvent)
{
e.target.parent.gotoAndStop(10);
}

This should help you resolve Flash / Flex Error #1061

Thanks and as always Happy Flashing
