Can someone comment on whether I am moving in the right direction when switching from procedural to OOP?
And another specific question: here I have a model instance used in every action, so can I immediately file it in the constructor?

Answer 1

public function stepTwoAction()
...
public function stepThreeAction()
...
public function stepFourAction()
...
public function stepFiveAction()
...
...
...
...
public function stepTwelveAction()

After stepTwelveAction() my eye twitched and I couldn't count.
Are you just kidding?
