Method jump_to does not redirect

[mjtribble]

I use the session to persist data from each step rather than persisting in the DB. This seems to mean I cannot use render_wizard to move from step to step because there is nothing to persist with a save method. Instead, I use jump_to to redirect to the next step after an update.

Example Wizard Controller

class MyWizardController < ApplicationController
  include Wicked::Wizard
  
  steps :uno, :dos, :tres

  def show
    jump_to(steps.first) unless step
    render_wizard
  end

  def update
    send(step)
  end

  private

  def uno
    session[:test] = params[:test]
    jump_to(:dos) # also jump_to next_step
  end

  def dos
    session[:test2] = params[:test2]
    jump_to(:tres)
  end
end

On the first render, a step is not defined. The jump_to function redirects correctly to the first step's URL /wizard?uno. However, specifying a step to "jump_to" in the update actions, in my case, just re-renders the current step /wizard?uno instead of /wizard?dos.
Manually calling redirect_to redirect_to wizard_path(next_step) || redirect_to(:dos) works.

What am I missing here? Thanks for your help.
