Description

If I create an alert with the static method Alert.show("msg", "title", Alert.YES | Alert.CANCEL, this, closeHandler, null, Alert.CANCEL) and press the escape key when the Alert is open, I get the following error

RangeError: Error #1125: The index 8 is out of range 2.
at spark.components::Alert/onKeyDown()[/Users/erik/Documents/ApacheFlex/git/flex-sdk4.14.1/frameworks/projects/experimental/src/spark/components/Alert.as:841]

The error occurs in the onKeyDown function in spark.components.Alert.as:

private function onKeyDown(e:KeyboardEvent):void {
if (e.charCode == Keyboard.ESCAPE)

{ removeAlert(identifyButton(_buttons[ _defaultButtonFlag ] as Button)); }

}

A workaround is to not pass Alert.CANCEL as the defaultButtonFlag, BUT this prevents the enter key from defaulting to the Cancel button, which is desired.
