Resubmitting remote form via AJAX -- old parameters get passed!!
When I submit a form via AJAX and get back some errors in my "errors"
div, if I try to resubmit the form with the errors corrected it still
passes the old parameters. See my code at: http://pastie.org/413269
(also pasted below). I can''t figure out why the 2nd time the form is
submitted, it still has the old parameters even though the fields are
populated with the new parameters. Anybody know why this could be?
## views/campaigns/_edit.html.erb
<% remote_form_for @campaign, :url => {:controller => :setup, :action
=> :update_campaign, :id => @campaign },:html => {:id =>
''campaign_form''},
:loading => "Element.show(''campaign_spinner'');",
:complete => "Element.hide(''campaign_spinner'');"
do |campaign_form|
%>
<%= render :partial => ''campaigns/edit_form_contents'',
:locals =>
{:form_type => form_type,:campaign_form => campaign_form} %>
<% end %>
## views/campaigns/_edit_form_contents.html.erb
<div id = "errors"></div>
<div class = "span-18 last first-row">
<div class = "span-2">
<img src = ''/images/1_25px.png'' class =

span-8''

Re: Resubmitting remote form via AJAX -- old parameters get passed!!
I realized that the form is actually sending the new parameters but I
shouldn''t be using a remote form here if I want a redirect...the
format.js {redirect_to setup_campaigns_path } doesn''t actually
redirect the browser.
