Hi  
I have in the controller

def sd\_activity\_attach\_file  
@sd\_activity=ServiceDeskActivity.new(params[:sd\_activity])  
@sd\_activity.save  
@sd\_activity\_attachment=ServiceDeskActivityAttachment.new(params[:sd\_activity\_attachment])  
@sd\_activity\_attachment.save

```
  responds_to_parent do
    render :update do |page|
      page[:sd_create_activity_ui].replace_html :partial =>

```

“service\_desk\_part/view\_sd\_activity\_details”, :object =\> @sd\_activities  
end  
end  
end

The problem is the database get updated but in any case  
view\_sd\_activity\_details partial is not loaded…I have an observe\_field  
in the file \_view\_sd\_activity\_details.rhtml…And the interesting thing  
is when I commented this observe\_field the page is loaded…WHAT may be  
the problem…I am attaching  
\_view\_sd\_activity\_details.rhtml

Please help

Your partial uses @sd\_ticket, but your controller isn’t defining it.
