----------------------------------------

             Summary: 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


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.
