Not sure if this is related, but it is a bit strange that your Frame implements
Application. Generally you'll implement Application in one class (e.g.
"MyApplication") and your main window in another class ("MyFrame").
MyApplication would then load my_frame.bxml, assign the return value to a
member field, and open the frame.
