**i got these errors, , more after those:

1046: type not found or not compile-time constant: progressbar.

1180: phone call perchance undefined method progressbar.

thanks in progress**

these errors occurred because there no progress bar component library. drag , drop progress bar component on stage , delete stage if don't required on stage.in way instance of progress bar component created library.
