undefined method `find' for Workflow::Event:Class

[gushonorato]

Hi,

I have the following classes on my system:

class Event < ActiveRecord::Base

  has_many :event_approval_requests

  belongs_to :user

  include Workflow  
  workflow do
    state :pre_registered do
      event :submit, :transitions_to => :awaiting_approval
    end
    
    state :awaiting_approval do
      event :approve, :transitions_to => :approved
      event :reject, :transitions_to => :rejected
    end

    state :approved do
      event :submit, :transitions_to => :awaiting_approval
    end

    state :rejected do
      event :submit, :transitions_to => :awaiting_approval
    end
  end

 ...

end

class EventApprovalRequest < ActiveRecord::Base
  belongs_to :user
  belongs_to :department
  belongs_to :event

  include Workflow  

  workflow do
    state :pending do
      event :approve, :transitions_to => :approved
      event :reject, :transitions_to => :rejected
    end

    state :approved
    state :rejected
  end

  ...

end

Note that the two classes have workflow definitions and one have a relationship with the other. In a view, when I try to access the event from the event_approval_request like below:

<%=h event_approval_request.event.title %>

I got the following error: NoMethodError in Event_approval_requests#index undefined method `find' for Workflow::Event:Class

this error doesn't occur if I access a non-workflow class, like below:

<%=h event_approval_request.user.first_name %>

Could anyone help me? Is it really an issue?

Thanks in advance,
Gustavo
