I am trying to create a new app ribbon just like the original invoice app ribbon.
I created a new app, named it InovicePL, and then created a new app ribbon as your online manual said.

It looks alright
Until I clicked my customized app ribbon. It gave me a error message dialog.
While the original one works good.
Please advise.
Thank you!
