If the exception doesn't cause any residual harm, you can always try to catch it with an UncaughtError handler.

It crashes in here: private function freeLinearElements ( elements:Vector.<IVisualElement>, oldIndices:Vector.<int>, newIndices:Vector.<int>, lastIndex:int):void { // TODO(hmuller): rewrite this, should be one pass (no indexOf) for (var i:int = 0; i < elements.length; i++) { const offset:int = newIndices.indexOf(oldIndices[i]); if ((oldIndices[i] == lastIndex) || (offset == -1)) { const elt:IVisualElement = elements[i]; if (elt) { freeGridElement(elt); elements[i] = null; } } } } The elements Vector (and thus the int i variable) is larger than the length of the oldIndices Vector therefore access to oldIndices[i] throws an exception at some point. I don't know how to catch this Exception in my Application Code - if this would be possible at all. To fix this issue I surrounded the loop with a try catch block and built a new spark.swf - absolutely not the way I want to handle this :( Should this be filed as a bug or is there any suggestion where I could tweak my application code to prevent this exception?
