problems with calendar_date_select

<% form_for @booking do |f| %>
...
<%= calendar_date_select_tag "datecome", "#{Date.today}", :popup =>
"force",:year_range => [0.years.ago, 1.years.from_now] %>

I just updated to Revision 333 (calendar_date_select) and prototype
1.6.0.
Sometime datecome is empty, sometimes it is set.

I also tried:

<%= calendar_date_select_tag "datecome", "#{Date.today}", :popup =>
"force",
            :year_range => [0.years.ago, 1.years.from_now],
            :name => "[booking][datecome]" %>

but this does not work, too.

Can somebody help?

That plugin has a good amount of documentation. Have you checked out -
http://code.google.com/p/calendardateselect/wiki/Documentation

I already read it - without success.
I switched to http://code.google.com/p/rails-unobtrusive-date-picker/

...and it works...it looks much more confortable to me.
