Hi All,

I got RJS error: TypeError: element is null while using ajax.

I used in view

<%= periodically_call_remote(:url=>{:action=>'get_user_list', :id=>'1'}, :frequency => '5') %>

in controller

  render :update do |page|
    page.replace_html  'chat_area', :partial => 'chat_area', :object

=> [@chats, @user] if @js_update end

in partial chat_area

<% if [email protected]? && !show_div(@chats).blank?%> <% show_div_id=show_div(@chats) %> <% for chat in @chats %> " style="display:<%= (chat.id == show_div_id)? 'block' : 'none' %>;">

    <% form_remote_for(:chat, :url => {:controller=>'chats',

:action=>'create', :id=>1}, :html=>{:name => "form_#{chat.id}"}, :complete=>"resetContent('#{chat.id}');") do |f| %> <%= f.hidden_field :sessionNo, :value=>chat.sessionNo %> <%= f.text_area :chatContent, :id=> "chatContent_field_#{chat.id}", :cols=>"100", :rows=>"6", :onKeyPress=>"return submitenter(this,event);" %> ')"/> <% end %>

</div>

<% end %>

<% else %> <% end %>

My div present in index.html.erb

      <table border="0" width="100%" cellspacing="0" cellpadding="0">
        <tbody><tr>
            <td align="left" width="80%" valign="top" style="">
              <%= text_area :chat, :chatContent,  :id=> "chatContent_field", :cols=>"100", :rows=>"6" %>
            </td>
            <td align="left" width="20%" valign="bottom" style="padding-left:10px;padding-left:10px;x" >
              <div id="chat_area">
                 <%= render :partial => 'chat_area' %>
              </div>
            </td>
          </tr>
        </tbody>
      </table>

Any help is appreciated.
