Subject: help on find over find

hi all

I have a problem trying to do the following:

MyModel.find(:all).find(:first)

it can look weird or unnecesary but this is the short explanation,
extended one is:

I have a helper method, this receives a collection an return some html,
this helper works fine if that collection is an association (has_many)
of a model but doesn't work if it is a direct find over a model

the error I receive is "LocalJumpError: no block given"

ultra mega extended explanation is:

a model:

class User < ActiveRecord::Base
 has_many :requests
end

other model:

class Request < ActiveRecord::Base
 def unRequested
  find(:all, conditions => {:state => "unrequested"})
 end
end

the helper
module ApplicationHelper
 def yearsCalendar (collection)
  years = collection.find(:all, :select => "YEAR(date_created) AS
years")
  years.each do |y|
   html << "<div>#{y}</div>"
  end
 end
end

finally at view:
<%= yearsCalendar(User.requests) # WORKS FINE %>

<%= yearsCalendar(Request.unRequested) #WONT WORK , RETURN ERROR:
"LocalJumpError: no block given" %>

any help?, thanks in advance
