model is nil

I tried to implement it and I got this error msg in console before render new form.

No model found in render args [{}]; model is nil

Same issue here. Seems to be sourced from render_with_hat_trick method in controller_hooks.rb. All the form fields are visible after view is rendered.

Output:
Making new wizard instance
new_with_hat_trick called
No model found in render args []; model is nil
Rendered vendor/bundle/gems/hat-trick-0.3.0/app/views/hat_trick/_wizard_meta.html.erb (0.9ms)

Also, submission of form results in the below. My model class is empty at the moment FWIW.
