> ActiveWindowManager, findHighestModalForm issue
> -----------------------------------------------
>
> Key: FLEX-34355
> URL: https://issues.apache.org/jira/browse/FLEX-34355
> Project: Apache Flex
> Issue Type: Bug
> Components: .Unspecified - Framework
> Affects Versions: Apache Flex 4.12.0
> Reporter: Alexander Mazuruk
>
> We have a lot of modal messageBoxes popped out on the stage, and we are
> trying to close them one by one, and for the second closed dialog we are
> facing this issue. Modal form was removed from the stage faster than
> mouseClickhandler from SystemManager was called actually.
> IChildList interface has .contains() method, Why in the world you are not
> using it?
> This code fragment must be fixed:
> private function findHighestModalForm():int
> {
> /////////////////////////////////////////
> var index:int = rc.getChildIndex(f as
> DisplayObject);
> if (index > 0)
> {
> }
> /////////////////////////////////////////
> }
> As follows:
> private function findHighestModalForm():int
> {
> /////////////////////////////////////////
> var index:int = rc.contains(f as DisplayObject) ? rc.getChildIndex(f as
> DisplayObject) : -1;
> if (index > 0)
> {
> }
> /////////////////////////////////////////
> }
> Otherwise we have this error pops out when we don't have a child in the
> IChildList and code is trying to fetch it out, but it's not there already.
> ArgumentError: Error #2025: The supplied DisplayObject must be a child of the
> caller.
