This is very basic and there are samples out there, but I am still struggling.

I need to fire an alert with a yes/no option.
I need to do this in actionscript.

Alert.show("Open new tab to search in Google Maps?",
"No places found", Alert.YES | Alert.NO, this, alertListener, null, Alert.NO);

function alertListener(eventObj:CloseEvent):void {

   if (eventObj.detail==Alert.YES) {
    Alert.show("You clicked yes"); 
    }
}

This returns an exception with the flash debug player:

TypeError: Error #1034: Type Coercion failed: cannot convert mx.rpc::AsyncResponder@e31c601 to flash.display.Sprite.

I have tried several variations of the code, but still get errors.
Apologies for such a trivial Q, but appreciate any help on pointing out whats wrong and the most elegant way of doing this.

Here is the code in its fuller context at pastebin (line 31).

    I should have persevered on my own a bit more.
    Code fix below:

    Alert.show("Open new tab to search in Google Maps?", "No places found", Alert.YES | Alert.NO, null, alertListener, null, Alert.NO);

                         function alertListener(eventObj:CloseEvent):void {
                             // Check to see if the OK button was pressed.
                             if (eventObj.detail==Alert.YES) {
                                 Alert.show("here"); 
                             }
                         }
