Double encoding of form action with form_remote_tag .. What am I doing wrong?

Hi,

I'm using a form_remote_tag(), except the parameters in the action attribute are receiving double HTML encoding.

Here's a version of what I've written:

<% form_remote_tag :update => "change", :url => { :action => 'change', :param1 => 1, :param2 => 2 } do |f| -%> <% end %>

The rendered action attribute becomes:

action="/ldun024/users/ldun024/password.html/change? param1=1&amp;amp;param2=2"

I've read over the documentation, here...

http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper.html#M000529

But it says form_remote_tag is like link_to_remote in the way you specify the URL, and I'm not sure what the difference is between my code and the example..

Thanks for any help,

Luke

Okay, I've got a fix, but still I wonder if I was doing something wrong, or is this a bug in the form_remote_tag() helper?

I wanted to have an action attribute in the form tag, so that I could reuse the ajax form in a non-javascript view and still have it work. Following the example in the API docs as far as I could tell my action URL was being double HTML encoded.

Adding a specific :html hash of options in the form_remote_tag, and within that specifying an :action attribute, using url_for to construct the URL, and passing url_for the :escape => false option has done the trick.

<% form_remote_tag :update => "change", :url => { :action => 'change', :param1 => 1, :param2 => 2 }, :html => { :action => url_for(:escape => false, :action => 'change', :param1 => 1, :param2 => 2) } do |f| -%> <% end %>

Still curious about whether this is the only way to achieve it? Seems incorrect to me.
