Hello, I’m in troubles trying to use ‘link\_to\_remote’ on Rails 2.1.  
Having this page:

#### Editing project
\<% form\_for(:project, :url =\> project\_path(@project), :html =\> { :method =\> :put }) do |f| %\> 

Name \<%= f.text\_field :name %\> Date \<%= calendar\_date\_select :project, :target\_date, :time =\> false %\> \<%= image\_submit\_tag('accept.png', :alt =\> "Update", :class =\> 'icon') %\> \<%= link\_to\_remote image\_tag('cross.png', :alt =\> 'Cancel'), :url =\> cancel\_edit\_project\_path, :method =\> :get %\>

\<% end %\> \<% form\_remote\_for(:project, :url =\> add\_contributor\_project\_path(@project), :html =\> { :method =\> :put }) do |f| %\>
#### Contributors
 Add contributor \<%= text\_field\_tag 'contributor' %\> \<%= image\_submit\_tag('add.png', :class =\> 'icon') %\> \<% end %\> \<%= render :partial =\> 'contributors', :object =\> @project %\>

And the contributors partial:

 \<% for contributor in @project.contributors %\> - delete\_contributor\_project\_path(@project),  
:method =\> :put, :contributor\_id =\>  
contributor.id %\>  
\<%= contributor.user.name %\>  

  
\<% end %\>

I get this error:

ActionView::TemplateError (You have a nil object when you didn’t  
expect it!  
You might have expected an instance of ActiveRecord::Base.  
The error occurred while evaluating nil.[]) on line #4 of projects/  
\_contributors.html.erb:  
1:

  
2: \<% for contributor in @project.contributors %\>  
3: -   
4: \<% link\_to\_remote image\_tag(‘delete.png’, :size =\>  
‘16x16’, :alt =\> ‘Destroy’),  
5:  
delete\_contributor\_project\_path(params[:project\_id]),  
6: :method =\> :put, :contributor\_id =\>  
contributor.id %\>  
7: \<%= contributor.user.name %\>

changing link\_to\_remote by link\_to the partial renders fine, but  
that’s not what I want. What’s the problem using link\_to\_remote in  
this context?, Which is the missing object?, if @project was nil the  
error would be at line 2, but it isn’t.
