You might have expected an instance of Array. The error occurred while evaluating nil.each Extracted source (around line #3): 1: <script language=javascript> 2: function select_html_code(the_id){ 3: <% for measurement_formats in @measurement_formats %> 4: if(the_id==''<%= measurement_formats.id %>''){ 5: document.getElementById(''<%= measurement_formats.id %>'').style.position=''static'' 6: document.getElementById(''<%= measurement_formats.id %>'').style.visibility=''visible'' # THIS IS MY CONTROLLER: def new @item_package = ItemPackage.new(:package_color_id => params[:package_color_id]) @measurement_formats = MeasurementFormat.find(:all) respond_to do |format| format.html # new.html.erb format.xml { render :xml => @item_package } end end the weird thing is that if i fill out the entire form, it''ll show no problems? any idea to this weird problem? thanks in advanced --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

My guess is that in your create action you are following the standard pattern of rerendering the new template if validation fails. However, in your create action you don''t initialize @measurement_formats, hence the error.
