Sequence.stop() does not stop active effect in queue

Flex SDK 4.1.0.14456

Calling stop() on a Sequence composite effect does not stop the child effect which is currently being played.

I tracked down the bug to SequenceInstance.stop(), where the variable 'currentInstances' is used even before it is declared. (Btw, why doesn't the compiler issue a warning here?)

// Call stop on the currently playing set
if (currentInstances)

{ var currentInstances:Array = queueCopy[currentSetIndex]; var currentCount:int = currentInstances.length; for (var i:int = 0; i < currentCount; i++) currentInstances[i].stop(); }
