Forum: Ruby on Rails undefined method join for STRING error

Hey all,

I was converting  a haml file to erb and when finished, I ran the app
and got this error message:

NoMethodError in Students#student_fail

Showing app/views/students/student_fail.erb where line #40 raised:

undefined method `join' for #<String:0x105a5e0c8>

Extracted source (around line #40):

37:
38:          <%  fields << render(:partial =>
"resources_partials/sequence/nav", :locals =>
sequence_info.merge({:cancel_url => {:controller => :dashboard}})) %>
39:
40:         <%= render_form { fields } %>
41: <% end %>

Thanks for any response.

Render form is defined in resources_form_helper.rb:

  def render_form
    %Q{<ul class="form">\n#{ yield.join "\n\t" }\n</ul>\n}
  end

Doesn't join require an array rather than a string?

I meant it is a method of Array not String of course.
