Try adding a high priority handler to the top-level window that parents that
scroller
topLevelWindow.addEventListener(FlexEvent.HIDE, hideEventFilter, true, 100);

Alex,
I've added systemManager.addEventListener(FlexEvent.HIDE, hideEventFilter,
true)
on the top-level window placed in a PopUpAnchor ( and containing checkboxes,
legends , group, scroller) and try to stop HIDE event, causing troubles in
FocusManager.
This tips prevents many exceptions, I see it in logs ..., but sometimes
SparkSkin of a scroller still produce the exception :-/
I don't undertand why, the scroller is in the displayList of the top
level-window but i'm not listening the Hide event, and then don't do
stopImmediatePropagation.
One more idea ?
Thanks,
Stephane

Alex,
yes the ViewStack is newly destroyed.
I use PopUpAnchor to show/hide Chart Legend, the bug is not clearly
reproductible, somtimes it appears, sometimes no trouble.
I'm still looking for a workaround. What should i do ? Replace PopUpAnchor and
use PopUpManager ?
Is it possible to plug my own FocusManager and a try/catch to hide the
exception ?
ViewStack, CheckBox and this morning I've got a new version with Group :

This indicates that the viewstack is not on stage. Is it being newly created

Sometimes the bug appears for ViewStack, CheckBox .... working with Flex

Any suggestions are wellcome,
