prototype not working with rails 2.2.2 ?

Hi,

i made an application using rails and prototype and all worked fine...
But today i upgraded rails to 2.2.2 and from that moment when i open
the webpage with firefox it gives me an error like "object is null"
and some prototype "helpers" doesn't work at all as for example the
observe_field...

Can anyone help me?

Thanks,
Riccardo

Hi, did you run the following command after installing the gem?

rake rails:update

-Conrad

Hi,

i did :

~/webapps/test/app/views/test$ rake rails:update
(in /home/citec/webapps/test)

but nothing changes

Firefox gives me an element not found error in prototyoe.js line 3588
and the observe_field ajax function is not working

Hi, what does the following commands produce?

gem -v

rails -v

-Conrad

gem -v
/usr/bin/gem:11:Warning: Gem::manage_gems is deprecated and will be
removed on or after March 2009.
1.3.1

rails -v
Rails 2.2.2

My code was

TEST
<br>
<div id="text">CIAO</div>
<br>
<%= select_tag 'direction[]', options_for_select
(@directions), :multiple => false,:class=>'list'%>

<%= observe_field 'direction[]', :url => { :action
=> :observe_field_test },:frequency => 0.25,:update => :text,:with =>
'direction[]' %>

now trying to change it to

TEST
<br>
<div id="text">CIAO</div>
<br>
<%= select_tag 'direction', options_for_select(@directions), :multiple
=> false,:class=>'list'%>

<%= observe_field 'direction', :url => { :action
=> :observe_field_test },:frequency => 0.25,:update => :text,:with =>
'direction' %>

seems to work....

but i don't understand why....
