Is it possible to pass this FormBuilder object to a controller and then back to a partial?

I have a form rendering a partial that i would like to update with a call to my controller based on user selectable parameters, but when the AJAX comes back, i get this error message because i cannot pass a form builder object between the controller and the view:

"undefined method `text_area' for "#<ActionView::Helpers::FormBuilder:0x12c4038>":String"

My View looks like this:

<% form_for @phrase, :action => 'foo' do |@f| -%>

         <%= select_tag(:language, options_for_select(["Chinese","English"],                           :onchange=> remote_function(:with =>                           "'language='+this.value",                           :update => 'slang_form_partial',                           :url => {:action => :something, :form => @f} )) %>

     <%= render :partial => 'forms/slang_form_partial'%>

<%= @f.submit %>

In my controller i have something that looks like this:

  def something       @default_language = params[:language]       @f = params[:form]       render :partial => 'forms/slang_form_partial'     end

Is it possible to pass this FormBuilder object to a controller and then back to a partial? Rails 2.1.0 and Ruby 1.8.6.

What you are doing can't work. You can't pass arbitrary ruby objects
as params to a url.
