Rails - Mar 2008 - Requesting help on Ajax link_to_remote RJS error

I am trying to make a remote call to an action when I click a link on
one page.

I have ''books'' and ''haves'' models. I have
''my_controller'' . In the
index.rhtml I have a link ''Add a book''. I am trying to replace
the
add_form in the same div where the list of books has been shown. When
I click the link  my form is showing twice along with some try catch
blocks saying an RJS error. However I am not having any RJS involved
in it.

Could somebody help me to resolve my problem.

Any help is very appreciated, and thanks in advance.

my index.rhtml code is

============================================================<%=
javascript_include_tag :defaults %>
<div class ="havediv">
   <div id = "newhavediv">
     <div class="heading">
        <h1>Books I Have </h1>
        <h3><%= link_to_remote ''Add a book'', :update
=>''newhavediv'', :url =>{:action
=>''new_own''} %>  </div>
</div>
</div>
============================================================
My controller code in action ''new_own''
============================================================def new_own
   @new_book = Book.new
    render :update do |page|
        page.replace_html "newhavediv", :partial =>
"new_own"
    end
end
=============================================================
my new_own.rhtml code is
=============================================================<%=
javascript_include_tag :defaults %>
  <% form_remote_tag( :url => { :action =>
''create''},:update
=>''newhavediv'') do |form| %>

                <p><label for="book_title"
class="left"> Book Title</
label>
                    <%= text_field ''newbook'',
''title''  %></p>

                <p><label for="book_author"
class="left"> Author</
label>
                    <%= text_field ''newbook'',
''author''  %></p>
   <%= submit_to_remote "Submit", :url =>{ :action
=>''create''}, :update =>''newhavediv''
%>

   <% end %>
=============================================================
I am getting the following error when I click on the ''Add a
book''
link. The form and textfields but it is not showing the submit button.
=======================================try {
Element.update("newhavediv", "
\n

Well you do have some rjs right in the render :update block. You  
should both pass :update to link_to_remote and use render :update.
It looks like your new_own action could just be render :partial =>  
''new_own''

Thanks!  Fred

But I don''t have any rjs code in :update block. I am passing :update
to link_to_remote and using render :update. I am new to Ajax though I
have done rails and ruby programming before. Could you please
elaborate more on what should be doing? ?As I understand, I am already
doing what you suggested me. Or I am missing or my bad.

Thanks

Oops, I meant ''You shouldn''t both pass :update to
link_to_remote and
use render :update'', quick slip of the keyboard there. And you do have
rjs in your :update block (what do you think page.replace_html etc...
is ?). Like I said if your action just renderered your partial it
would probably be ok (although if you are expected render :partial =>
''new_own'' to render new_own.rhtml, it won''t. It will
render
_new_own.rhtml)
