my error, my usage was based on this link (form builder tab): http://electronicholas.com/calendar

ArgumentError in Sales#new

Showing app/views/sales/new.html.erb where line #14 raised:

Extracted source (around line #14):

Which version of CalendarDateSelect are you using? I have version 1.15. I found something similar in the bug tracker. Maybe you have an old version and if you update it will be fixed?

I have tried in my app using CalendarDateSelect in a form builder with embedding and it works.

<% form_for @project do |form| -%>
  <%= form.calendar_date_select :starts_on, :embedded => true  %>
<% end -%>

I get this on the page

<input id="project_starts_on" name="project[starts_on]" type="hidden" />
<span id="cds_placeholder_11065" style="display: none; position: absolute;"></span>
<script type="text/javascript">
  //<![CDATA[
    new CalendarDateSelect( $('cds_placeholder_11065').previous(), {embedded:true, year_range:10} ); 
  //]]>
</script>

Make sure you put the includes at the top of your page/layout

<%= calendar_date_select_includes -%>

I suspect you should have used calendar_date_select_tag there, instead of calendar_date_select.
