The wizard that creates Wizards should register the Action that it creates (if the type is 'Static') in the layer and the Action should extend AbstractAction instead of CallableSystemAction.
Maybe even better to implement ActionListener, which is also what the New Action wizard does.
The current content is intentional. While in some cases you might in fact wish to launch the wizard via a globally registered action - in which case you should simply run the Action wizard to set up the details - in other cases the wizard should be launched based on some other trigger entirely. The generated Action is merely a demonstration of how you could launch the wizard, not intended to be final code.
