nUI6 Alpha : Stance Bar not displayed when switching specs..

[Xrystal]

I have nUI6 Alpha and nUI+ Release both latest as of 30 minutes ago.

Switched Disc Priest spec to Shadow Priest spec but no Shadow Form stance button appeared. Possibly connected to the pet bar situation with the two bars being connected at the moment.

/nui rl resolved the issue and the button displayed

If I then switch back to disc the button disappears as expected but the button holder is still there. Switch back to shadow again and it displays find.

Supposition:
The problem seems to be linked to the fact that if the bar frame isn't visible then there is a good chance it will not display the buttons linked to it when they are needed.

Suggestion:
Perhaps have the bar frames visible but click through and transparent until they are needed - or something similar that will work as close to what we are expecting.

Screenshot 1 - Going from Disc to Shadow the first time - notice no place holder for the button visible
Screenshot 2 - Going from Shadow to Disc - notice that although the button disappeared the place holder is still there which enables it to display correctly when you switch back again.
