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,

Hi Shandy,

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, Bill
