You say your container is a DisplayObjectContainer. Is it also a Flex Container
such as Canvas or VBox? If so, there is a bug with using swapChildrenAt() and
maybe with swapChildren() as well. Try using removeChildAt() and addChildAt()
instead.
A Flex Container does tricky stuff with child indexes and overrides child
management APIs such as numChildren, addChildAt(), removeChildAt(), etc.,
because there are two kinds of children -- content children and non-content
children. If you write
<HBox>
<Button/>
<Button/>
</HBox>
there are only two content children but, if the HBox has a background or
scrollbars, there can be additional non-children children.
I think what happened is that the swapChildren() and swapChildrenAt() methods
got added to DisplayObjectContainer in Player 9, and the Flex framework is not
yet supporting them properly in the Container class.

Hi Matt,
Sounds like there's a problem with flex updating the screen before the
children are swapped properly.
Try validating the component after the call to swap the children, and
catching any exception thrown.
try {
container.swapChildrenAt(ind,1);
container.validateNow();
}
catch (err:Error())
{
}
Does that make any difference?
Best Regards,
Ciarán
