AS3 Warning: 1090: Migration issue: The onRelease event handler is not triggered automatically by Flash Player at run time in ActionScript 3.0. You must first register this handler for the event using addEventListener ( ‘click’, callback_handler).
AS3 Warning 1090 Description:
So the other day I opened some AS2 files that I use for teaching Flash Arrays at UVU. I changed a few things in the file and tested my movie. That is when Warning 1090 popped up and I realized that I had missed a few things. AS3 Warning1090 is the most comprehensive and complete error message that I have ever encountered in Flash or Flex. Not only does it give a really clear description but it tells you how to solve the issue. Kudos Flash programmers/writers. Jen DeHaan if this is you – Nice Job!
P.S. This will also happen with onEnterFrame, onPress, onMouseMove, etc… I have only included one example here but it applies to all cases.
Flex / Flash Error #1090 Fix:
Do exactly what the message says use an event listener instead of the onRelease event that was common in AS2.
Bad Code:
joinArray_btn.onRelease = function () {
//Do Something
}
Good Code:
joinArray_btn.addEventListener(MouseEvent.CLICK, joinArray);
function joinArray() {
//Do Something
}

This should help you resolve Flex / Flash Warning #1090
Thanks and as always Happy Flashing
