Thanks for the huge amount of advises. ;)
As it appeared the hole thing was in method hidePopUp of PopUpWindow.
We do removePopUp there and after it focus of course changes and this
pop-up fires focusOut. in focusOutHandler we call the very same
hidePopUp. But, it isn't popped up now. So the only thing missing in
hidePopUp is test for isPopUp. The final code for hidePopUp is
following:
public function hidePopUp() : void {
if (isPopUp) {
PopUpManager.removePopUp(this);
}
}
That's all.
