setButtonIcon looks like to not working properly

Hello,
I have made some months ago a GUI for my game, I save my code on a Git, my hard drive crash and lost all data :frowning: . I restarted to code my game based on the last backup of my Git, and I download new jME 3.0 and the new tonegodGUI, the problem is it looks like buggy:

  • My text field becomes black after they lost focus
  • The setButtonIcon, does not works when I call it more than one time.
  • The window title are black

Is there a reason of it ?

I still have these problems, if someone have got any idea to solve them I will be happy to know…
