Ahem.

Emmanuel, when you run this program, you are correct that it raises an 
exception. Did you notice which line of code the backtrace was pointing 
to? ;)

The exception that is raised in your onCmdOpen() method is being caught 
by the 'rescue' block at application.run. The code in that 'rescue' 
block raises yet another exception, though (hint: what does 'self' refer 
to in the call to FXMessageBox.error?).
