RJS sporadic error message


#1

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:

Travel Arranger Pages

The profiles for which you are responsible

<%= render :partial => 'show_my_users' %>


<%= render :partial => 'add_new_profile' %>

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 -%>
Type in username to add to your list:

<%= 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:

<img id="bull" src="bull.png /> </div> <p>this will work:<br> page.replace_html “bull_ring”, “new_image.png”</p> <p>this will not:<br> page.replace_html “bull”, “new_image.png”</p> <p>I’d start by taking a look at the HTML in Firebug prior to hitting the<br> submit and compare what’s there with what you need wrt your RJS.</p> <p>HTH,<br> Bill</p>
