Rails - Apr 2009 - RJS sporadic error message

I have this form that allows a user to enter a username and save it,
assocciating your profile with theirs via an id. A list gets updated and
a partial is displayed. The problem is that when I hit the submit button
to this form to make this all happened I (sometimes, but more often then
not) get an RJS error that reads:
  TypeError: Cannot set property ''innerHTML'' of bull.
I hot OK and another error pops up giving me this long string of what
appears to be JavaScript or Ajax code?

Main View Code:
<div id = "update_first" align = "center">
  <span class="header">Travel Arranger Pages</span><br
/><br />
  <b class = "table-header">The profiles for which you are
responsible
        </b><br />
  <hr width = "67%">
  <div id = "travel-managers-users">
    <%= render :partial => ''show_my_users'' %>
  </div>
  <hr width = "67%">
  <br />
  <div id = "company_users">
    <%= render :partial => ''add_new_profile'' %>
  </div>
</div>

Partial - add_new_profile:
<% form_remote_tag :url => {:action =>
''add_profile_auto'', :id =>
@user.id },
  :complete => "new Effect.Appear(''airport''); new
Effect.Pulsate(''airport'');"
  do -%>
  <b>Type in username to add to your list: </b><br />
  <%= text_field_with_auto_complete :user, :username,
     {:value => '''', :size => 45},
     {:url => { :action => "auto_complete_for_user_username",
        :id => @user.primary_account_id },
      :skip_style => true} %>
  <%= submit_tag ''Add Name''%>
<% end -%>
....

Controller code - add_profile_auto:
.....
   render :update do |page|
     page.replace_html ''travel-managers-users'', :partial =>
''show_my_users''
     page.replace_html ''company_users'', :partial =>
''add_new_profile''
   end
.....

Any ideas of why I am getting this error. I am just lost. Like I said I
sometimes get the error and sometimes I don''t.

Thanks in advance,

I''ve never seen this myself but can offer some general info / advice.

In reverse order, yes.  What you''re seeing in the error dialog is the
javascript that was being attempted when the error was encountered.

The fact that you''re getting a ''TypeError'', and the
error itself is
telling you that bull doesn''t have the property you''re trying
to set.
It looks like you''re using replace_html on something that has no html
''insides''.  For example...

assuming:
<div id="bull_ring">
  <img id="bull" src="bull.png />
</div>

this will work:
page.replace_html "bull_ring", "new_image.png"

this will not:
page.replace_html "bull", "new_image.png"

I''d start by taking a look at the HTML in Firebug prior to hitting the
submit and compare what''s there with what you need wrt your RJS.

HTH,
