I am using http://code.google.com/p/calendardateselect/ to make
date-selection easier.
This is my current code. I''d like the selection of a date to trigger
the
observe_form and call the partial to be rendered.
My current attempt is to update a hidden field within the form when a
date is
selected, because plain date selection did not seem to work.
Did I just screw up the observe_form / form_remote_tag setup?
Is there a better option for date selection which will easily trigger
the observe_form?

class DictatedExamsController < ApplicationController
def index
@users = User.all
@from = Date.new
end
def filter_widget
text = ""
params.each { |a, b| text << "#{a} => #{b} <br />"}
render :text => text
end
end
