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 :
TypeError: Error #1009: Il est impossible d'accéder à la propriété ou à la
méthode d'une référence d'objet nul.
