Unfortunately got deferred because we didn’t have a real-world, but simple test 
case.  Do you have one?  It seems to be caused by something not being on stage 
and having visibility flipped.  I think one user was binding visible to 
something that was supposed to evaluate to true, but didn’t always because the 
binding chain wasn’t fully created.

What does your call stack look like?

Hi,

I too am getting the DisplayObject(form).stage.focus = null error.  In my case, 
I’m using a PopUpAnchor to show and hide a form.

Is there a definitive fix for this?
