Subject: [ActionFlow-User] help: actionflow didn't work for me,T_T
Message-ID: <464AAF24.2080406@poppyrr.com>

hi everybody,
i just tried the actionflow plugin but it didn't work for me. i
installed the plugin through:

script/plugin install svn://rubyforge.org/var/svn/actionflow/trunk/action_flow

(the attachment is a screenshot of the installed folders),

for next, i pasted the demo controller code on the wiki into my
controller and change the controller'name to 'Sell', here is the code:

============

class SellController < ActionFlow::Base
start_step :init

end_step :quit

view_step :init do
on :next => :second_step_init
end

action_step :second_step_init do
on :next => :second_step
upon 'ActionFlow::ActionFlowError' => :init
end

view_step :second_step do
on :next => :quit
end

view_step :quit do
end

def init
state[:status] = 'Woohoo, I just inited'
render :action => :init
event :render
end

def second_step
state[:status] = "I'm displaying the second step..."
state[:just_to_remember] = 'I got through !!'
render :action => :second_step
event :render
end

def second_step_init
state[:status] = "I'm initializing the second step..."
if rand(2) == 0
event :next
else
raise ActionFlow::ActionFlowError
end
end
end
=============

next,i started the server, and type the address
http://localhost:3000/sell/. and then i got the error:

=======

NoMethodError in SellController#show

undefined method `start_step' for SellController:Class
